fix the WORST SOUNDING EXHAUST with a ONE SIMPLE CHANGE?

[@LawrenceTolman]

Seems like I'm never satisfied with the sound of any exhaust, but this one has me second guessing myself on the choice of muffler. I like the overall tone of the sound, but its got just a bit too much volume.

[@craigdonalson4634]

magnaflow has a kit to tune out drone. kevin from the utube channel lite brite did a show with richard on his drift vette that eliminated the drone

[@hydrocarbon82]

The J-pipe is going to be the best return on time investments here, short of a OEM jumbo muffler & e-cutout. You'll be able to get that 2200rpm frequency with a phone app and tune most of out out. Your truck definitely has the space for it.

[@frankhempstead9671]

You might like the 50 series flowmaster better.

[@BrockGrimes]

20:13 Sounds A Reeeeeeal Nice.

[@BrockGrimes]

I plan on putting a Nascar style boom tube on my '88 OBS....oh and i'm in my 40's, LOL

[@handothemagnifico]

Move the resonator to the front of the system. The drone starts up front and travels down the pipe. Also it will bring the flow master sound back. If you have ever done a cat delete and kept the same muffler you will get the drone. Yet if you leave the cats but remove the muffler it sounds good in the cab still. I just fought this on my Audi s4. They make resonated down pipes for this exact reason on the Audi. Hope this helps.

[@klampykixx]

Do u feel the resonators handle the engine heat ok up front? Im currently planning my jeep exhaust and have a couple ideas floating.

[@handothemagnifico]

@@klampykixx Yes they do actually. The car gets driven pretty hard and they have been solid for 2 years now. The drone inside the car was really bad at highway speeds. The mufflers at the back did make a difference but it had the harmonics up front that created the annoyance inside until I resonated the downpipes. Night and day difference in the driving experience of the car.

[@AdmiralRustyShackleford]

@@handothemagnifico A lot of vehicles use resonators in the rear by the bumper, so they must work back there. A resonated downpipe is just to make up for a cat delete, not because it's the best possible placement of the resonator in the entire system. An example is the Charger/Challenger. People do a rear resonator delete only, and they drone. They do a center muffler delete only, and they don't. Every car and truck will be different, depending on the rest of the exhaust system. Personally, I would just add another smaller resonator in front of the muffler or since he has duals in front of it, 2 small ones further forward.

[@handothemagnifico]

@@AdmiralRustyShackleford he had a truck. The drone in a car and suv will travel threw the trunk space. That's why they use resonators on gm suv in the rear but not on the pick ups. The drone passed the cab is not nearly as bad due to the bed space allowing it to escape. If his cats are gone then he needs the resonators in its place to reduce the cab drone. I only used my Audi as a small example. I own a performance shop and experience this often. I use resonators in the crossover pipes when I need to stop the drone in a ls pick up. 👍

[@AdmiralRustyShackleford]

@@handothemagnifico The newer Silverado uses a tailpipe resonator, as do the Hemi Rams, since they came out in 03 or whenever. Drone isn't just vibration it also comes from the exhaust frequency and volume so any resonator no matter where it's placed will change the sound.

[@AustinCoulson]

That's the best ending i've seen in any of your videos. Totally relatable story, I am also becoming that old guy. I also like to imagine one of your neighbors watching you set up a tripod to record the engine revving in the middle of the street and having no idea what's going on.

[@henrybrundage7186]

[@rroop1973]

I can appreciate what you're doing with the exhaust. I think is sounds great wide open. Keep the videos coming.

[@Davesroadsidescraping]

I'm 68 years old and love the way my 1998 5.2 Dodge Ram sounds. It has a single with a Cherry Bomb 3in outlet w/ a turn out in front of the right rear tire. Nice bark! I love loud exhaust.

[@ZippoVarga]

I'm with you LT.....I don't want to hear or feel the drone inside the cab, but still want that classic SBC sound. Cheers! Zip~

[@chazgeisler6213]

Your not getting old! When I was 16 I wanted quite exhausts on my ls swapped blazer

[@mikespencer9409]

Beautiful sounding exhaust. Pure music. I've run high volume exhaust systems for years & apparently I don't know what drone is. All I've ever heard is the engine humming along. Yours is pure beautiful engine music.

[@mhrepoman]

If you used some exhaust wrap it can help with the exhaust resignating. Some other stuff you can do that will make a big improvement is to install some sound deadening mat on the interior of the truck. Do the floor. Doors, back of the cab and roof. That will make a HUGE DIFFERENCE!!! Then do a spray in bed liner. I recommend the Rhino Liner brand (like the actual Rhino Liner, not some knock off). The reason is because it is more of a rubbery material, rather than something that is really gritty and rough. It is also applied thicker. I used to work for a rhino Liner dealer and it is sprayed at 1/4" thick on the bed floor and 1/8" on the sides and tailgate. It does an amazing job at deadening the bed from vibrations and rattles. Nice job on the exhaust!

[@chrisadamson8082]

I've been looking for a '00 '01 Silverado regular bed regular cab for a long time now and I've finally got a good lead for a decent truck. This build series gives me hope. Now i need a welder cause I'm gonna want to get my exhaust perfect. Thanks for the good/bad influence. Now i need more tools money and time. Oh by the way my wife doesn't like you cause of these videos, gives me too many ideas. And ideas cost money as she says

[@fortyshooter1]

Those Pro Series mufflers are excellent! I run a dual 3 inch setup using a pair of those on my 427 Windsor powered 1985 Mustang LX. Over 35 years of owning the Mustang this is the quietest system I have had on the car. I also run the Flowmaster D flow mid pipe which is like a mix of an H and X flow setup. I run short tailpipes that exit at the rear of the tires but not to the bumper. Very quiet for 560 HP and no drone at all!

[@stan4930]

I had the same problem when I built my exhaust for my Honda. It was really hard to get all the drone out of it, and it is still a work in progress after about 5 revisions...oh well, it's fun to do the work anyway! Love the TIG welds everywhere. It's a skill I haven't had the chance to learn yet. Cheers!

[@NXT_LVL]

Nice! haha Yeah my dad says if it's too lout you're too old. But there's a big difference between loud and sounding good vs take two Advil. The Spintech 6000 I have is right under the backseat (being a quad cab) haven't tried to see if theres a big difference with the seat up or down. All I know is if I'm in heavy traffic going slow 10-15% throttle it drones... from like ~1,100rpm. If it does start to drone I just tip in a tiny bit and the drone shuts up lol Stock manifolds, cats into a Y 2.5" single side exit into a Y split tip slant cut 4"x19" between the back of the cab and the rear tire.

[@jesseoliver9061]

I love the way it sounds even now with the resonator ! I’ve dealt with drone a lot on diesel trucks . I’m curious just for a test you could try. If you have a test piece try extending the end so it’s past all body parts . Nothing for it to echo off of or under .

[@jeffwooton7138]

As always, awesome content. A couple of things I could suggest. 1) Dynomax UltraFlow Round muffler, 22" long, in 4". About 85 bucks at Summit, nice deep sound. I enjoy it. You are like me though, and have a preference on sound. 2) Yes, a Helmholtz resonator will kill the drone. You should need one about 22" long. 3) Take a minute to research that shock relocation thing. They are on opposite sides to minimize axle wrap. When you go turbo on that truck, you'll need all the help you can get, unless you plan on CalTrac's or something similar. Thanks for posting, and keep the content coming. I'm enjoying it.

[@aaronschocke5463]

Are you talking about traction bars?

[@dirtcheapgarage3869]

Aaron, cal-tracs are far superior to traction bars. In addition to stopping the a pe twist, the twisting motion is converted into downward motion with caltracs. Therefore planting the tires and preventing axle wrap

[@chriswright7710]

Sounds really nice,and I'm a 58 year old teenager so of course it does.When I bought my 98 Sierra it had a catback exhaust that droned at around 1800 rpm start,I didn't mind too much but unfortunately while driving with my wife and kids I couldn't quite make out what they were saying,not such a bad thing.lol

[@kailuagarage]

You really are good at exhaust fab! Maybe that guy from Magnaflow that was always on the TV shows doing custom stuff can hire you haha

[@jn7154]

I feel the same way about wanting a quieter exhaust. I must also be getting old as I just replaced my flowmaster super 10 di/do with a magnaflow di/do. Much more bearable. I just finished putting my bed back on my truck after cleaning and painting the frame, replacing a few bed supports and welding on new bed sides. As a Mainer, you'll understand the struggle we have with rust

[@BryanBeast13]

The exhaust sounds very old school, like a flathead kinda. Happy new year LT thank you for all your content and knowledge sharing. I've learned a lot from you, thank you

[@LawrenceTolman]

Happy new year and thanks for watching!

[@michaelbrown5601]

I like quiet performance too! I’m trying to tame the 1600-1800rpm drone in my cammed 2012 Caprice. J-pipe is my only option as I’m all out of mufflers. Have you ever experimented with helmholtz resonators? You keep the volume but kill the drone.

[@curtjeziorski350]

I have 3" solo streetrace cat back setup. The j pipe is awesome. There is still some drone at certain rpm.i haven't really fine tuned it yet. But I love the setup and sound. Having the x pipe also helps some

[@michaelbrown5601]

@@curtjeziorski350 I’m running long tubes into dual 3” with Magnaflow x-pipe muffler with dual Magnaflow mufflers in the back. Drone is killing me! Is your j-pipe adjustable?

[@ChevyARt15]

I have a 2013 Caprice, but with an LS3 cam. The Solo Exhaust j pipe is adjustable.

[@Fendamonky]

@@michaelbrown5601 a j-pipe is tuneable based on the length of the pipe. Essentially what you're doing is finding the correct length to create a sound wave at 1/2 the frequency of your drone. As that pulses back through your exhaust it will effectively cancel out the noise/drone of that particular frequency. Calculations have been done for length based on most piston engines.

[@raze4789]

I feel the getting old thing. I used to do headers and single chambers into turndowns on everything. I had guys telling me what setup to run on my 5.4 f150 but they all sounded like trash. Muffler delete on stock exhaust is perfect. Good cold start, decent idle, quiet cruising then about 1900rpm up it barks well enough. And it's cheap to do.

[@chandlerlofton6536]

I think I’m going to run a dynomax ultraflow welded on my stroker project truck. I’m going to daily drive it so I don’t want anything to wild. I think it will still sound cool with 11:6 compression and a 225/232 cam. I like your set up because it doesn’t make that clap sound most trucks have!

[@SlikLizrd]

I ran a pair of DYNOMAX UltraFlows on my CrownVic -- Straight-through power -- perfect pitch -- and NO DRONING at any steady speed. Wasted a ton of money on Flowmasters -- NEVER AGAIN !!

Love the vid LT, keep up the content. It's amusing to realize the things you want quieter on something you drive a lot as you get older.... Tires... stereo... exhaust...

[@EricFixalot]

Tailpipes make a huge difference. I once cut the mufflers off of my car so it was straight piped ending in the middle of the car. Got tired of it and added tailpipes going straight out the back still without mufflers. It did wonders but the car was still droney so I added hellcat mid-mufflers/resonators and it sounds pretty good. My car came with a factory x-pipe and has some drone at around the same rpm. I’ve driven the same car with an H-pipe conversion and it sounded way better. Also I’ve noticed that large diameter exhausts are harder to quiet down.

[@loyetemple7193]

I had a flow master on my Tahoe and I had the same problem with drone and something else was the amount of heat coming from the muffler so I decided to go with a borla xr1 race muffler not only did it reduce the amount of heat but I no longer have a drone problem and it sounds really good I actually like it better than the flow master !!!!!

[@Ezzeenow]

The best way to keep your mufflers and get rid of annoying drone is J- pip. Really good vids on KZbin on the subject. Length of pipe is everything.

[@shanedavault210]

I'm with you, when I was younger open headers was fine with me. Now a complete exhaust it's to loud and drones like crazy.

[@Man_of_TheWay]

I had a 6.0 lq4 with a decent cam, Doug thorley tri-y headers, xpipe, 3" true dual exhaust, and dual Magnaflow 14 inch body mufflers with basic dumps before the axle. Swb single cab. Easily the best sounding exhaust I've heard personally.

[@coupalr1]

I used a resonator from a 3.5 ecoboost on my off road only 🙂 First Gen Ford Raptor. It made a huge difference.

[@jengel451]

In the same boat. Nothing I do with the exhaust is perfect. I finally played with a helmholtz resonator on my v8. I was a bit skeptical at first but once I put it on truck I became a believer, it's crazy how well it works. No drone, zero, nada, zilch. Do the calculation, get yourself some pipe and weld it on. Stupid simple.

[@SuperDriver379]

At 18 I was all about straight pipes and now at 30+ decent sound and being able to talk without yelling at each other in the cab has a value. I’ve found a muffler with a nice tone but mild in cab noise after many years of trying everything. I keep a Dynomax 17698, in my shop at all times. along with a few flowmaster S bend kits. There is a longer case (17789) I use them on my tow vehicles, dump mine right in front of the the bumper similar to how this truck was done. I’ve found that way keeps it quiet inside like a tailpipe but much harder to ding and bend keeps the rear tire from beating up the pipe.

[@gtrider316]

Had a similar situation on my fbody. Resonator and different muffler helped but still droned a bit. Added sound deadening material inside the car and it made it much quieter not only from the exhaust but road noise and vibrations as well.

[@LawrenceTolman]

I'll have to add some to this truck for sure.

[@TravYFZ]

Awesome! I think it sounds better now. Looks slick with that slash cut too!

[@Bikedueder]

Nice fab skills! The exhaust looks badass, and sounds fantastic. I am with you though on the excessive interior noise. I have the opposite issue however. It is loud in the cab while accelerating, and cruising at a steady speed, it's quiet. 2014 F150 STX 5.0. I ordered a premade Dynomax single three inch stainless exhaust with an Ultra Flo welded muffler. The entire resonator was missing from the kit, and that was how it was supposed to attach to the original cat pipes. I took it to an exhaust shop, since the WHOLE idea was bolt on and I could install it in the driveway and weld it up. For a resonator, he spliced a stainless steel glasspack in, then ran the extra provided pipes back to the muffler. The tailpipe fit like a glove and hit the hangers dead on. But the weird part is that cruising at ANY speed you hear almost nothing, but accelerating even softly produces a loud throbbing pulsing bombombombom sound. I am pretty sure I will get used to it after a while, but I saw where a guy soaked some header wrap and wrapped his muffler with it, which seemed to help.

[@Swagmoney696]

Axle dumps drone like crazy. I finally did an over axle and tail pipe on my truck as well.

[@MrArrakis9]

you should consider adding sound deadening material to the back wall in the cab and to the floor that will really quiet down the interior resonance

[@13Dixiefried]

That was my thoughts as well.

[@LawrenceTolman]

I'll have to for sure

‘72 C10 454 Hooker Super Comp long tube headers 3” collectors --> 3” Dr Gas X-Pipe with 2-1/2” exits --> Flowmaster Delta 40’s --> 2-1/2” tailpipes straight out the back..... In my opinion, and many others, this is the best sounding truck in the great state of Texas!

That sounds so much better than the generic exhaust everyone has put on their trucks!

[@DirtyDanMunicipalMan]

Man I wish I could weld like that! That exhaust is just rad. If you were gonna change mufflers, maybe look into some large Magnaflow style mufflers. They’re straight thru and are known to be on the quieter side with not much drone, plus very free flowing.

I would be interested to see if you extend it 4” past the bumper and straight back if it would be better in the cab, I’m with you with drone exhaust

[@anomamos9095]

Tip Record your irritating exhaust system with a good digital recorder. Put the file into the computer and note what frequencies are worst. Search for a reference paper on tuning exhaust systems for sound and se what is required to kill those frequencies. It’s been years since I’ve done anything like this so don’t ask for specific information. I have used it to create a tuned length resonator. This is jut a length of pipe joined into a convenient place that is closed off at one end.

[@johnboticki9154]

Vibrant resonator, the big ones, are always the way to go. That said, I am curious about the helmholtz resonators, and specifically to design them. Should have paid more attention in engineer school I guess.

[@EGGINFOOLS]

Yes on vibrant. I have the muffler on my non catted 4.8 RCSB and I love it.

[@300blkaac]

I made a helmholtz resonator for my old 2gr-fe Camry. Did a great job at killing the drone where I had it but it also decreased the overall volume a lot more than I expected. Looking back at it I would have just put on those vibrant ultra quiet resonators

[@Turbogto_guy]

I tried the vibrant resonator. Did not fix the drone. It took helmholtz resonator (j pipes) to fix it.

[@dirtcheapgarage3869]

I’m the same way. Picky as heck with exhaust too. My favorite so far I did is the 2.5in x-pipe with single chambers to a side exit on my ranger. I’ll have to send you a video in an email or something. It sounds very different from most 302 mustangs I’ve heard. I know tailpipes make a huge difference in how the sound reverberates. Also, going from 3 up to 4 inch makes things drone more in my experience, even when going through a Y.

[@mcbridemotorsports5788]

I'm getting the same way with exhaust. I have a 97 Comp T/A I've owned since 06. I installed LT Headers/Off Road Y-Pipe with a resonator to pre axle dump as my exhaust setup. I have the car up on jack stands as I have the motor out (Going 396 CI) I'm redesigning the exhaust system with a E-Cut out so I have have a nice tone while cruising but can also be annoyingly loud if the mood strikes me.

Dumps are worst setup IMO. I hate owning a vehicle I love to drive that I can't stand to drive. I've done it before and regretted it immediately. Friends builds samething. They'd swear that's what the wanted no matter what I said. We get it for a ride and the look on their faces all said the same thing. "Oh shit, this sucks. I can't even hear the stereo". Resonators and mufflers out the bad from now on Plus 100lbs of sound deadening. Makes all that hard work worth it and enjoyable. Again this is just my opinion. To each his own. Truck sounds great. I'm with your dad on this one, quiet power. No idea where you live but it's beautiful.

[@ThanenJ]

Liking the new exhaust sound. I understand not wanting that drone in the cab, it can be brutal.

[@EGGINFOOLS]

Still sounds great. I think the resonator should have been before the muffler. IMO. My 4.8 RCSB has the 1900 to 2200 sound as well. Just no drone. When I had the dynatech bullet muffler with axle dump it was obnoxious in that rpm range. I don't have cats. I put a vibrant on it and ran the tailpipe to the factory location and man what a difference

[@Carl_Jr]

A couple of things . . . The resonance is caused by the diameter and length of the pipe. Think of it like the difference between a trumpet and a trombone. A trick I was shown in shop class back in HS was to weld a small piece of metal to the pipe similar to balancing the driveshaft. It'll help stiffen up the pipe and it won't bellow as much. Another option is one of those flex pipes with the woven metal used on a lot of FWD cars. Those help fool the pipes into thinking they're shorter and will change the resonance frequency.

[@moldingpro7208]

[@OronasGarage]

The end of the video is my favorite! I am also very picky about my exhaust and have had a pair of flowtech shorty headers sitting in my garage because I have been really thinking of how I want to do the set up of my 2500. It has the true duals from factory and I have been wondering if it would be beneficial to do a Y-pipe and make it to a single pipe all the way back similar to how you did. Waiting for you to start selling one off exhaust systems 👌🏼👌🏼

[@1stAxelKain]

Helmholtz Resonator was the best thing I ever did on my 454 suburban to cure my 1800rpm drone. take a little math and fab work, but very easy and incredi8bly effective! I need to do a video on it...

[@blackhawk7r221]

Try 3” flexible conduit. The lack of a smooth inner wall surface kills the resonance problem and often eliminates the need of any muffler at all.

[@bluecollarhotrods9781]

It certainly tamed it down quite a bit. I have 2.5" lead pipes coming off the headers on my truck, dynomax race bullets X 2. Then a two in, one out - large case Magnaflow. It's a dual 2.5" in, single 3.5" out muffler. I have a 3.5" tailpipe exiting in the factory location. It's really tame at idle and cruise. Sounds pissed off at wide open throttle. A few times I thought that maybe it was too quiet, but after any kind of long trip... I know I made the right choice. I have an LQ4 with a small cam. I did the same LQ4/80E swap to my father's GMC Sierra. Slightly larger camshaft in his truck. Same headers, 2.5" dual pipes all the way to the factory location. Two 14" case Magnaflow oval case mufflers. It was really raspy and unbearable. I added two resonators similar to what you used. It cleaned up the sound, but still a bit too loud for my 71 year old father. I'm about to switch to a dual in/dual out muffler with a longer case than those 14" deals. Praying that it tames it down to the desired level. If not, I am going to rip it all off and start over.

[@johnbarker5009]

I really appreciate how you show us that sometimes you don't get a perfect result on the first try. I did see something slightly alarming, though, and I almost hesitate to mention it because you're a far more experienced welder than I. I'm really concerned about your use of brake clean as a metal cleaner for welding. If not thoroughly dried and vented that stuff can create some extremely dangerous gases around welding. It may even say so on the label of the can.Lacquer thinner, acetone, or starting fluid/ether are better. Btw, even on the video I like the sound better. As always you do great work.

[@LawrenceTolman]

you're right about the brake clean, but I believe the major issues is if you use the chlorinated stuff. they only sell non-chlorinated brake cleaner around here, so it won't make the dangerous phosgene gas. BUT yes, acetone it still the best bet and is what I normally use, but I was out at the time.

@@LawrenceTolman OK. I was just alarmed you might be endangering yourself. Sure wouldn't want that to happen. Thanks for answering.

Sounds nice LT, mad welding skills 👍👍👍

Thanks 👍

@@LawrenceTolman lucky me I get to replace the heater core on my 81 Z28 next. Will be adding a Tremec TKX 5 speed, March Performance serpentine system, and a rear disc conversion !

On my cammed crew cab i did a 3.5 inch y into a single 3 inch dynomax . Equal length merge at tailshaft, no drone and no more rasp. The eqaul length is key on a cammed truck. Ever notice how g8s or camaros, Corvette's sound ao good... Equal length..

[@russelltrupia4479]

I think it sounds GREAT. Happy New Year LT

[@josephhall6399]

Seems like instead of changing the volume of the exhaust coming out of the tailpipe, you could change the amount of sound coming into the cab. A little sound deadening material might help with the droning, vibrating panels.

[@terryjohnson8978]

Sounds great!! I wish I had the patience to build my exhaust on my dually. I had a muffler shop do it and it really looks bad. One of these days after I finish the rear end 4-link upgrade I may just have to just give it a shot.

I appreciate all the videos you make I learn alot n I always save em all so I can study by wat hing them all so thanks from Hawaii n a Happy New Year Aloha

[@deadbrian9247]

Always sucks when you have to change exhausts that soon after setting one up, but I'd be lying if I said I hadn't had to do it myself.

[@yamahaguy1732]

I don’t do anything fancy because I like to change it up a lot however I like my setup now I have Blackwidow venom 250s which are pretty quite for cruising and I have cutouts for when I wanna be loud

[@deadbrian9247]

@@yamahaguy1732 I've considered some black widows. What vehicle/motor is yours on.

[@jd440]

You should look into aeroturbine mufflers and resonators. They have mufflers with the resonators already in it. If it's still to loud or not to your liking you can always add on another resonator. I haven't used flowmaster mufflers for two decades now. They don't seem to help flow much or help with performance. I have a pair of 2525 aeroturbine mufflers and ar25 resonators near the tips and love how it's sounds on my hemi magnum rt. Think you may like the aeroturbine better. Might also squeeze out a few more horses too.

[@Man_of_TheWay]

I will say that sounds pretty good. Love all the tig welding.

Depending on the space you have available, a parallel helmholtz exhaust resonator tube is more effective at eliminating drone than a pass through type resonator.

[@davidterceira7451]

What is a parallel helmholtz exhaust resonator tube. Just quick description. Thank you

[@YeetxBoi]

@@davidterceira7451 you could've typed it into Google instead of that comment homie ngl

[@joshuaszeto]

@@davidterceira7451 a helmholtz resonator is a tube that branches off from the main exhaust pipe. Its capped on one end and basically reflects the sound waves back into the exhaust and cancels out the target sound frequency. You generally measure the frequency you want to eliminate and then add an appropriate length helmholtz resonator. There is a more precise formula to calculate the appropriate length. Although by my quick research, generally, the larger the helmholtz resonator, the larger the range of sound frequencies it will cancel out. Best part about these resonators is that they do not introduce any sort of flow resistance. If you want to see what they look like, search most civic type r exhaust systems. Most of them seem to use helmholtz

[@north4961]

Totally 👍 Helmholtz is the best! Ran 3 inch x 42.5 inches with a 3 inch 90 degree elbow and capped towards rear to eliminate 93 Hz drone. This was for a Ram Ecodiesel 👍👍
