Thanks for all the suggestions about a resonator but we already installed one when we built the original exhaust!

[@nicholasmarlow4359]

just sent it no silencer! im excite to hear my car start up for the first time. Ktuned Ram Header to 3" Magnaflow cat, Vibrant Ultra Quiet Res and Turndown muffer.

[@PNWSV]

Header to 2-1/2 straight pipe no cat no res and a 40 series Flowmaster is how i roll

[@VanWinger]

I was thinking a jack handle or breaker bar would make the bends in the hangers just as easy as whacking with a hammer but this method gets the job done all the same.

[@thebarber7197]

I like the virbant ultra quiet resonators to knock down drone. Due to their length they eliminate resonant frequencies in 4cyl from 2800-3200rpm.. Had one on my 03 vibe GT and will 100% use it again.

[@dyllman98]

Speed Academy love the shirt!

[@inspyral02]

I used to run an A'PEXi Active Tail Silencer when I had a 3" exhaust with my turbo setup. It was nice because it was closed and quiet at idle/low throttle like a traditional silencer, but at higher revs and WOT it would open and have very little restriction giving you the best of both worlds. I would highly recommend it if you want to be quiet while cruising around and not rob power when you floor it. The only real downside is that they are kinda pricey for "just" a silencer.

[@flyingbricks1602]

What I say when my girl asks me what are we doing tonight 2:59

[@96blackjacket]

🤣🤣🤣

[@ryan_riffs]

The Vibrant "Super Quiet" resonator is a great choice too. I put one on and could not be happier. No power loss and sounds like a stock Honda. =)

[@rafaelavila9571]

Ryan Riffs yup! I have a Megan 2.5 inch on my 240sx no cat. It sounded good but was getting me in trouble. One vibrant super quiet later and it sounds awesome and quieter without any real reduction in flow

[@Joe.0oo]

Hey guys, do you have any sound clips? I bought two of these to put on my straight pipes 2.7tt fusion, and I wanna know how much more I want to kill the sound

[@olorb2618]

@@rafaelavila9571 what trouble?

[@looncraz]

You can tune the sound more by modifying the silencer. You can drill some holes, shorten it, or even reshape it (pretty difficult to get right, though.. and little room to work). If you're going to drill holes, you can start with 1/3~1/2" holes about 1" from the start of the upstream opening and go smaller as you work your way towards the exhaust end, increasing the distance between each set of holes drilled to address different wavelengths of sound. This is partly how muffler work to tune sound form the factory. If you're going to cut it, just cut off half an inch to an inch at a time. The tone should shift slightly each time.

[@Inthirath]

18" magnaflow resonator from any muffler shop put a hush on my 3" real nice, made it even deeper. no rasp at all.

[@warrentopping5764]

loved the 930 TURBOKRAFT build series....second to none this channel is awesome!!!!

[@hondoctorkh2398]

Helmholtz resonator is a great thing to reduce the loud without power loss

[@The_True_]

Pro Spec PT nails it again! Sweet looking stealth muffler setup. Best part for me was... PT: "I'm going to use this Milwaukee tool..." *shwiiiiing* (cuts like butter) "That's a good tool!" Lol! Better than mine, it feels like I'm in a war movie using a machine gun regardless of what I'm cutting. 😂 My hands then shake for a day after using the reciprocal saw. Milwaukee should give you a sponsorship, this is like the second or third time you have demonstrated Milwaukee's awesomeness. Where are you at Milwaukee? 🔧➡🚗📹➡📈⬆💲⬆😊 It even makes sense in hieroglyphs!

[@damienfokkema6963]

The True i use milwaukee gear as a diesel mech and i havebt broken any yet help up to lots of abuse including being pretty much submerged in water oil and grease

[@The_True_]

damien fokkema Sounds like a solid product. I use whatever's cheapest at Harbor Freight, and deal with the occasional tool drama. But on a low budget, HF is the way to go. On a good budget, looks like Milwaukee is worth the cash. Good to know.

[@tireflipper8000]

Haha daily on R888Rs and worried about exhaust noise. I love speed academy you guys are great! Turn down ftw!

[@seyed7705]

I have the same 3 inch exhaust setup with the ktuned turndown muffler. All I did was added 2 vibrant ultra quiet resonators and that made it perfect with no drone, quiet when daily driven and aggressive when I floor it.

[@samotrx7]

Any sound clips? I have the same setup but with 2 bullet style resonators and the drone is killing me

[@rogerserafin]

Loved the videos of this build. Thanks ya guys.

[@RonsRides7601]

How do you just not love this guy???

[@GarageSupra]

I have a HKS 3" inlet to 4.5" outlet cannon on the back of my supra with a full 3" straight through turbo back exhaust and I use one of those silencers in my cannon and it makes a huge difference but I can't boost it with it in there but for rolling home late at night into my quiet neighbourhood it's perfect and takes seconds to install and remove.

[@jfv65]

Droning is caused by standing waves in the exhaust at certain rpms. I would try adding a helmholz resonator somewhere just infront of the rear axel. These don 't hurt flow.

[@malakiblunt]

i agree , and there not even hard to make

[@therealboofighter]

I was going to say the same thing.

[@mrclown7469]

What you're all more than likely referring to is a 1/4 wave resonator, not a Helmholtz resonator. A 1/4 wave resonator is a simple pipe with a length tuned to 1/4 the length of the sound wave, which it bounces back for another 1/4 wave, making it a 1/2 wave at the entry. Since a 1/2 wave is 180° out of phase it cancels out the soundwave. A Helmholtz resonator is shaped more like a beer bottle with a neck and a cavity volume, which resonates with the correct rate of airflow, much like blowing on a beer bottle. Huge difference in how difficult they are to design and build.

[@G12m]

Goodness! The 3" Vibrant StreetPower sounds glorious!!!

[@ariesr4883]

Same setup as mine :) love vibrant since their debut.

[@OFFAxisBuilds]

that sounds awesome. Good job on the video. if you wanted to quit it down a little more you could wrap that silencer tube with some exhaust packing. but all in all it sounds really good

[@Kohju]

Turbo 😋 best "silencer"

[@alexsurh1472]

It really is especially for 4 cylinders

[@lukeellis4828]

Not true at all mines loud as shit and droney on highway and I am turbo b16a

[@josephmaldonadojr4692]

I mean considering he's just going for something easy to make it nice for daily driving and take out for the track it seems perfect to me gonna try this out 👌

[@brooksanderson6837]

try motorcycle baffles, worked very well on my old w202 kompressor after straight piping mid section left a bit of drone. Added the baffles at end of super44 muffler and it created a nice unique sound with no more drone. cheers!

[@marquisjamie]

Is it just me or did the silencer make it louder and more rice sounding than just the exhaust before

[@angrysocialjusticewarrior]

EXACTLY.

[@daviddunn3296]

I feel like the mic adjusted to be louder Because there's less bass but I feel like it sounds better just a little raspy

[@40motomike]

💯 it did.

[@anarchyamp]

Yup sounded louder WITH the silencer

[@chicanoforever9005]

YOUR RIGHT MAN!!!

[@CaptianAwesome20]

I had a full race 3" coming off of a skunk2 alpha header on my FG2 and it was just way too loud. So I remembered how well borla treated me when I had lincoln mark VIII. To my suprise they made an exhaust for my car that would bolt up to my header but it was 2.75". Long story short I spoke with borla and they convinced me that it would make the same power if not more. It does, I picked up an average of about 7hp throughout the rev range 2hp at top rpm and in some places I was making 15-20 more hp in the rev range. It looks like a stock R18 exhaust and sounds beautiful when you get on it but its super quiet 90% of the time. ***I did have to do some tuning for this result but it was not much***

[@MrBaconstrips13]

Hey guys! ChrisFix here!

[@banecker1]

Forgive the ignorance, but is this Chrisfix? I noticed his shirt and now I can’t tell if it’s him or my brain thinking man sure does sound like him. Lol

@Adamofalltrades That's not Chris no

[@PhillyDee215]

Lol I just put a 3" exhaust on my 3.8L check the video out but now I think it's too loud lol. I a need a muffler to quiet it down but can't be restrictive. Cool video👍

[@ChutneyInc.]

Thanks Alot! For sharing this!

[@MattyK166]

It'd probably be easier to bend those exhaust hangers by slipping some 30nb black pipe over the top...leverage. Loved your box and stand solution...worked perfectly.

[@agenti4393]

2:33, classic ChrisFix shot!!! 👍

[@ChrisHondaProductions]

Nice install!!!

[@benzoape9622]

Add a resonator and leave the silencer out. I had a lot of drone on my brz setup but I switched to an invidia resonated front pipe and the drone was reduced for sure. The black muffler looks better imo. Definitely keep it.

[@gametechbuilds3755]

wow what a nice build

[@jeffreymoore4132]

Have you thought about 2.5" with a hemholtz resonator ala s2000? You're not going to lose that much hp and the improvement in quality of life I'd argue is well worth it.

[@etnies88]

Flowmaster on my evo sounds pretty good. Give one of those a try.

[@Jeffball610]

I prefer the deep tone, but it can drone. The best option is to add a resonator or "tuning tube". (Subaru using a small tube typically after the cat) Both can tune out the "offending frequency". For my car with a full 3" exhaust and just a turn down like you had, I simply put a turbo on the exhaust manifold. It quiets it down quite a bit, and actually gives it a bit of a horsepower increase ;-) #4G63510

[@pFbSpecV]

Another series finished!!

[@poonasor]

you have any recommendations for what I should do if I have the k-tuned turn down muffler if the silencer isnt going to work? you think a vibrant ultra quiet resonators would do the trick?

[@colins4732]

Did you guys consider using an XForce Varex muffler? It looks like a good design with the option of adding bluetooth or OBD2 to control the exhaust noise.

[@xxMidNightHuskyxx]

I had the same thought, would be perfect in this application.

[@akbarmarma2655]

Have you try the Apexi noir muffler @speed academy?

[@FPAUTO]

The Ktuned mufflers look really good, either type. Would personally prefer the stainless finish though

[@YNTGUNS]

Ok so any ideas how to quiet down my 2016 mustang gt? Longtube headers, no cats 3in parallel pipes into resonators and then magnaflow mufflers. Any ideas to bring my volume down?

[@pupsnbugz]

Got my exhaust replaced yesterday. Stock 04 Acura tsx went from being a very low roar to extra bass. Normal with aftermarket exhausts? Thanks. My mechanic also installed my driver side muffler with a pretty significant tilt to the left, so...not too pleased. Gotta get a hold of them today.

[@howardcrider10]

So that’s what you look like!! You sound what you look like two thumbs up!!!👍🏻👍🏻

[@frankmanson5876]

Great science 👍

[@heatseeker_]

Any axleback recommendations for a 2014 Lancer

[@leeroy60]

You could have put a v-band or used a wide band clamp to be able to swap between the mufflers if you wanted. I have a similar setup on my integra. I used a slip fit connection. So I can swap between a quiet muffler and my Apexi N1. Just takes a wrench and a couple minutes to unhook the hangers.

[@Jack-gl1tw]

Love the shirt man 😂

[@crakkhausemotors5021]

Good Job Done.. Was The Cat Converter On Still..??

[@lloydrobinsoniii]

Where did you get your triple gauge pod? It’s clean under the stereo deck like that.

[@ChutneyInc.]

Its better without the silencer. I think more drone came from the silencer. I think the only way to tune a quiet sound is to focus on the piping diameter and what resonators and mufflers work the best. The Vtec may be more noticable without the silencer. 2.75" piping may sound better for most 4-cylinders but im not done testing yet

[@mondomoleno.3404]

I have a Megan OE-RS exhaust on my car, and it sounds barely above stock (which is what I wanted). Some people have said it's a knock off of the Greddy Spectrum Elite, but I don't see the similarities at all (for 2nd gen "GE" Honda Fits). The Megan is quieter, the muffler is bigger, placed differently, and comes with a silencer as well (which makes it sound stock). Long story short, I couldn't use that turndown cannon.

[@TomB1988]

Neat job :)

[@edwardpeter2652]

do you weld tig AC or Tig DC is also good?

[@BlackyBrownDestruction9337]

You need to put in 5 copper dish washing scrubs inside plus wrap inside the silencer with sink drain net so it doesn't fly out. It's very quiet that way.

[@FroilanJosephChavezJourney]

Does it still have a resonator? Wonderful video by the way!

[@MiniMan68]

Nice tiggs bro !!!

[@JimTonic79]

[@ricardosom7766]

I have a 95 civic with a crazy noisy exhaust that leaves me deaf after a ride. What would you or any of your viewers here recommend me to do? To completely make it silence. I mean just the regular sound like any car that’s not modified does. Because like you said using it as a daily drive it gets annoying.. thanks for your help.

[@LLSniper]

I'm sure anyone who has a loud exhaust can add a silencer, and I'm not trying to bag on your choice because it is a good one, but I do think it could have been interesting to see an aftermarket active exhaust solution as I can't seem to find anyone really adding their own system.

[@frkpwr]

I can’t recall, are you running a resonator before the muffler? Definitely sounds better, but I’d be curious to hear it with a resonator as well.

[@christophervtec762]

I have headers to a cat delete 2.5 " all the way back to a 3 chamber round muffler ending with a obx ovel muffler so the system sounds very low tone until high rpms, without the chambered muffler it sounded VERY canny

[@GrandmaKeith]

vibrant performance or jones exhaust makes some great resonators.

[@tassap9355]

[@engrishsheep]

in my teenager years thru mid 20s. I prefer the 3" straight exhaust without silencer. In my late 20s to early 30s. I can live with the same with silencer... Now, in my late 30s, I definitely would trade 50 horsepower for a nice sounded exhaust without any drone. (ex. something like the stock high-end performance car. It loud enough when at full throttle, but there is no drone when cruising on highway that kind of exhaust.)

don't weld hangers directly onto the body of the muffler. you should weld a piece of flatbar between each edge of the muffler and place the hanger there. this will rust out prematurely. source: work at exhaust shop

I have stock mufflers and qtp cutouts so you can get the loud sound when you want it but then it doesn’t drone on the highway when it’s closed.

[@alomechanthasinh4079]

What's the name of that Vibrant exhaust

[@BigJnWorldWide]

It's seems like you're good with welding and metal work. Maybe not a traditional resonator but maybe design a helmholtz resonator. If you measure the exhaust decibels at cruising speed, you can calculate the volume needed for a helmholtz resonator and it will work WORLDS better than what you did in this video.

[@dcrasta]

Old school motorcycle trick :: Wrap your silencer with some exhaust fiberglass. Use safety wire to hold the fiberglass in place. The more fiberglass/tighter you wrap, the 'mellow'er the tone gets. Takes away the metal-ting-ting sound . Could help reduce the mid-range freq boominess also. Another trick is drill some 1/8th inch holes in the pipe of the silencer. Wrap the entire silencer with metal exhaust wrapping. This metal wrapping will not blow out like the fiberglass, the holes add flow.

[@brodytunnell99]

Just wondering, why did you tig the pipe end and mig the hangars? Was it for a better seal where the exhaust connects?

[@speedacademy]

I mig the hangers because I can hold the hanger in place and use the gun with the other hand. With a tig it requires a lot more effort since you need two hands. I actually tig'd the hangers when I welded them on.

[@muinzakaria9292]
