Can't wait for all the experts to come out from the woodwork who "know better" Good job FMU very informative.

[@dcgeeked8917]

it's not that deep

[@mishaisspeed4081]

​It really isnt, you are right ​@@dcgeeked8917

[@carguy7627]

OJ, no exhaust sounds in the exhaust video? Come on man, give us the eargasms we all need!

[@darrylcavanaugh9465]

39K subscribers? REALLY!?!?! Tell all of your gear head friends to checkout this channel. Ojay is a badass. I wish I had a shop like this near me.

[@dannoyes4493]

Biggest frustration? Trying to get long tube headers & exhaust for a naturally aspirated, high revving, VG30DE in a Nissan 300ZX (Z32). Well done.

[@colorado.e9x]

I would love to see a before/after compilation of your megaphones

[@mishaisspeed4081]

They won't ever do this because it doesn't make a noticeable change

[@WiseGuyzGarage]

OJ, you really knocked this one out of the park. Straight to the point, easy to understand, and gave very valuable insight into how the exhaust system should be crafted.

[@-ev1l562]

First time seeing this chanel. Definitely earned a sub! I love how clear and concise your points are, no beating around the bush, no pulling punches. KZbin is in sore lack of this quality of content.

[@FluidMotorUnion]

Awesome, thank you and welcome!

[@PROTO_JK]

Great content. OJ the way you speak clearly, calmly, and confidently, you’re a natural for this platform. We are all lucky to have you and your knowledgeable team.

[@FluidMotorUnion]

Thank you so much 🤗

[@crystalzues4712]

Would love to see your guys take on one of the popular 4 cylinders such as B series. Very keen to see how your design ethic would change how they sound.

Yup! Facts

THISSSSSSS

[@AZ-hf9ow]

Your exhaust work looks amazing 👌😎

[@tramonsivis]

I picked up an n55 m235i and the previous owner put a v**f race exhaust on with a dinan performance midpipe. The system is lightweight and functional, but i knew that it wasn't meant for me long term and have actively begun searching on how or what I am going to fix/revise this. The tone and drone could have vastly been improved with tuned resonator, taking away that annoyance between 2700 and 3300 rpm. At some point in life, Id love to meet both you and alex from lsc, but more importantly, since im in the midwest as well, sometime have your team guide or build a way better "performance daily driver" exhaust. I love nice exhaust, but theres a difference between purpose volume and just loud and crass. Keep up the good work, hopefully a future client someday.

[@dodgejohnson5819]

I have an 06 charger R/T 5.7 hemi and am running solo performance 3” stainless steel no mufflers no resonators but have J pipes and sounds great

[@invo5]

Would love to see you talk about: 1. Four cylinder exhaust optimization (NA and turbo) 2. Ovalized exhaust tubing for low cars (yea or nay)

[@user-ti2eq8rj1w]

how about a decent 3.5 ecoboost sounding exhaust? Would love to see that from you guys!

[@MustangGuru]

Corsa extreme double X pipe is in my opinion the best sounding out there, which is what I have on my Roush stage3 supercharged car. And it has no drone at all. On my NA 2019 Mustang (wife’s) has the AWE track edition on it. Drones a little and has a deep tone.

[@FluidMotorUnion]

The customer had that exact system. Didn’t love it so he went searching. Got magnaflow next, hated that. That’s when he got us involved. Feedback from the last three weeks has been- “it’s the only system that’s done exactly what I wanted when I wanted… take when you cruise, LOUD when you get on it, a classy sound… NO drone!” More on that coming up in a few weeks

[@ryanpooler3962]

Awesome video, OJ! The exhaust topic is a tricky subject, and oftentimes was regarded as sorcery and black magic in realms of old....😂 Your exhaust "code" is very, pardon the pun, sound. [Dad jokes anyone?] There are so many rabbit holes on the subject that you can dive into, and it would be neat if you untangled some of those in future videos. I loved your magephone segment a few weeks ago! I am currently building a radical custom exhaust from alpina type headers back on a BMW e53 X5 I6 (rare manual transmission) with some really cool hat tricks and some modular sections for experimental sound tuning. Rabbit holes. Everywhere. 😂 Love the channel, man!

[@cr500_conversions]

I can't wait to dig into my ATS-V. The Borla system is awesome, but the LF4 has notes that remind me of a Porsche, but the Borla doesn't promote it.

[@jemery3]

Turbos, my exhaust needs turbos 😂

[@1FiftyOverland]

I wanna see what magic you can do with a 2.7 or 3.5 ecoboost f150 exhaust.

[@nickom7828]

I was looking for someone, if no one asked then I was going to lol. I'm up in Wisconsin so not far away from them!

[@joslaleb_]

My question has always been where to place the mufflers and megaphones throughout the system. How does the position of these change the tone of the exhaust? Is it better to have megaphones at the beginning of the system, in the middle or at the end? How does the length of the megaphones affect the performance and sound? Is it better to have mufflers at the end of the exhaust system or in the middle? It would be great to know that information with the help of your experience. Great video!

[@FluidMotorUnion]

Megaphones are really trial and error. We have been able to do a lot of that. There are so many combinations depending on the vehicle's set up, your goals, as well as space constraints.

[@samuelho3289]

GT350 sound clip please!!

[@yamman93]

You guys really hit a home run with this one. Excellent video filled with information that is presented in such a way that makes it very easy to understand

[@FluidMotorUnion]

Glad you enjoyed it!

[@tedjones-ho2zk]

I would like to see a high flowing exhaust that sounds as quiet as stock on a fox body mustnag. My current exhaust that I have use a couple of Dynomax VT mufflers that do a great job in getting rid of drone, and that's with a magnaflow high flow catted system. Is it possible to have a non-catted system, that flows without being much louder than a stock system....

[@7000U9ZHIFT]

Yeahh ,I use hush thrush mufflers on LS3 with 2in longtubes and catless x pipe... sounds great without obnoxious

[@jasminemunoz539]

I wanna get this exhaust system been hearing your work 👍 love it

[@WaldemarPerezJr]

Alex brought me here. I was just researching after market exhaust for the Mustang.

[@johnelopez5482]

Very informative content. Thank you for sharing.

[@ricardopontes9373]

Great content man. Discovered the channel a week ago. I live in Europe and in a near future thought of ordering an Exhaust from FMU for my GTI. I understand it's not perfect as would be better to have the car in the shop. Unfortunately I can't. There's a lot of stuff on the market but sounding thin can plus questionable performance when that gets into the dyno.

[@jarebb1]

Thanks for the great videos lately.

[@kyleolin3566]

Great video. Tons of relevant information packed into a relatively short video.

[@Neggs2000]

Where this is most apparent is the VG30DETT Nissan. I love them, but the exhaust note is awful with an H-pipe and way more smooth and exotic with an X-pipe. Awesome video, thanks for sharing your experience. This is for real performance enthusiasts.

[@benganey3924]

Biggest frustration- paying top dollar for Hooker Aero chamber DUAL 3" in 3" out muffler just to find out it necks down to a SINGLE 2" inside😢

[@barborisov]

So what about a vr6? Should I use an x pipe first and then merge into a y pipe or straight into a y pipe like the factory did?

[@sofiyactually]

Seriously thank you so much! This is the most informative video on exhaust I've ever seen. Wish I could get an exhaust system from you guys but I live all the way out in California. Keep the videos coming!

Better sounding exhaust for subaru cvt since the 2.4 turbo is going into a few vehicles now but still livable because of drone

[@narekpapukyan5455]

The quality of content and knowledge on this channel is unmatched. Also, IMO critical when working with metals that expand due to heat, especially stainless, invest in ADJUSTABLE MEASURABLE torque wrenches & use the proper thread liquid (if/when needed, such as anti-seize or threadLocker) Torque bolts AT spec (not over, not under), in a cross-bolt pattern. Great stuff 👍

[@dabjeb09]

New to your channel and very happy to find experts in the field. I will be coming to you guys for my next build. Thankfully not too far away in Ohio LOL. What has been your experience with Venturi pipes? Many years ago, I had a 2007 Mitsubishi eclipse GT with a 3.8 l V6. I built a custom exhaust four times to get it right. Unfortunately it was the year before they switched to a dual exhaust design so an x-pipe wasn't in the cards. In the final build, it was the Venturi pipe that got me over the 300 WHP mark. I was pretty happy getting from 263 BHP to 300 WHP and still being NA. I am glad I stopped there because was starting to follow this wild Russian guy who frankensteined the Evo AWD system into his 4th Gen eclipse and went forced induction. My fabrication skills aren't that good lmao. Neither was the $10K price tab to pull that off.

[@____MC____]

I just finished my first full stainless with the right welding wire and gas this time. Ugly but functional welds. I had to use pie cuts to find different angles in 3 spot. I found myself using tape to hold them in place then peeled some back to tack. I noticed any angle cut pieces elongates the hole size and doesnt match exactly. Had to cut apart one section after it moved an inch off. Found welding my way back was better. Learnd cheap v bands are trash. Learnd v bands warp and need to be filed flatt. Came out okay. Made my own x pipe out of 45° to keep a low angle and didnt over cut the middle to cause a pinch point.

[@HisNameIsTater]

The ugly butfunctiona got me rolling. If they are ugly I doubt they are functional. On a serious note if you are serious about learning to weld look to any technical college close to you most offer classes for hobbyists.

[@____MC____]

@HisNameIsTater ugly meaning not perfect dimes. Not 1st timer low amp globs stuck together on the surface. The inside had a weld line where you can see different metal.

[@williamheidbrink2411]

I have a 750-800 whp 15 sti I have a 3 inch awe track exhaust on there now I like the loudness off it but want to see what else is out there and what size I should need for it also Has to be a quad tip no muffler

[@albertoxp03]

thoughts on exhaust wrap next? i have long tube headers im waiting to throw on my 06 gto

[@ketillundsrensen6167]

Previous owner have changed the exhaust and overtighten all U-bolts so the exhaust leaks a bit. Just waiting on my new header so I can put in a anti backflow piece and make the rest of the system silent and non leaking.

[@ericn7698]

Great video! Really well presented and informative. You have a new subscriber!

[@FluidMotorUnion]

[@stevelibby3]

@fluid motorunion what are your thoughts on two mufflers vs one? I have a BMW X5, single turbo with full bolt-ons... planning to install either a pair or a single Valvetronic muffler. I'm assuming there's going to be a significant difference in sound between the two but I'm interested in the choice that would have higher flow/hp.

[@Coyote9smilespergallon]

Can we order these mufflers and Xpipes for the 22Mustang GT like shown?

[@davidvu4366]

opinions on adding valves onto an exhaust, specifically after the cat before the res?

[@Duuhvis]

Man, I’m about to drive up and have ya make me an exhaust for my GR Corolla. I bet you could really make that boosted 3cyl sound more unique

[@allenpaley]

Nice! Any systems for an Audi MK1 TT?

[@cosmogstr]

One question I have is how does changing the shape of a pipe, for example to oval pipe affect performance and sound? Does it have much of an effect or is it just a little more difficult to work with?

[@lifeishard1211]

my 1982 Chevy S-10 has a 6.0 liter V8 with long tube headers, 3 inch collectors that connect to dual 3 inch pipes with Flowmaster 50's. It sounds good but it's too loud. I don't have an X pipe. the mufflers have a center in and offset out and that's how I get the exhaust over my rear end. I have some ideas but I would like to know what you would suggest.

[@Machinama12]

OJ, that’s a pretty distinct Chicago accent you got there. lol I have a C7 Corvette with a Procharger. My car does NOT have the NPP muffler. I’ve wanted to upgrade to a Corsa NPP system and was interested in your opinion.

[@adrenanic5871]

Great advise as always. What are your thoughts and recommendations about adding a valve system to an exhaust?

[@FluidMotorUnion]

We like it when you are looking for more than one sound option

[@SprayIgniteBoom]

Cool BUT at the end of the video you should have started up the cars!!!

[@user-iy3sq7wx3z]

I want a quiet and good flowing, i know i have to compromise but i don't think straight through mufflers will make my exhaust quiet enough

[@PeterTron]

What if you have a civic and a two 90 degree bends? Where along would you place a vibrant resonator to help reduce drone best?

[@thomashalley7258]

3 inch x pipe with headers. That it. Have fun.

[@yucannthahvitt251]

1. Size (the "1" per 100hp" rule of thumb which makes me lol with my 700bhp I6 through a single 3.5" turbo back) 2. Minimize use of bends 3. X pipes make a V engine sound better and improves scavenging 4. Material (he uses expensive stainless) and thin wall 321 sounds better 5. Straight through mufflers and multiple resonators can control drone and sound better than chambered mufflers 6. Weld quality makes it last and backpurged TIG with good fit up makes for a nicer exhaust system and minimizes turbulence in the pipe 7. V bands are better than bolted flanges

[@Pinko_Jess]

Turbos are an exception to that rule, I think. They extract a lot of energy from the exhaust gases, so it’s possible that they’re not moving as quickly in a turbo system

[@yucannthahvitt251]

@@Pinko_Jess Mass flow is mass flow. NA or turbo the same gas flow will have the same requirements of pipe size, Q=AV. Post turbo the density of the exhaust flow won't change significantly vs what it would be at the collector of a header in an NA engine. EGT will be a little lower for the turbo engine post turbine vs the NA engine's collector, really the only difference is that the pressure waves and scavenging effects are basically irrelevant after the exhaust exits the turbine.

[@chadpennington4594]

absolutely sir! just subbed and liked. Curious, I have a new catback I installed, the flanges do leak and are known for it. Would it be bad thing to have someone cut and weld so I can change to vband? I have a Greddy Evolution GT for my 370z... very pretty, love the sound....terrrrrrible sealing ability on all flanges.

[@upsidedowndog1256]

Nice! I have an 07 Ridgeline and the muffler is getting a rust spot, what muffler would make the V6 sound good without sounding like a fart can?

What wall thickness do you recommend for 304?

[@anthonylezada8532]

The Audi 3.0T supercharged engine is known in the Audi community to be difficult to make sound good once you throw test pipes in the mix. I’m curious as to what you’d do to get it to sound awesome not only at WOT but also at low throttle city driving with a full custom setup from the header back. All my 3.0t friends and customers who run test pipes either have something custom to combat the ugly rasp, volume and/or pitch as there really isn’t a system out there on the market people are 100% happy with….

[@mally94]

What is your view on taking an inline-4 equal exhaust headers and making the headers uneven?

[@hamletxxx1363]

What do you do for AWD Escalade?

[@RandomGuyDan]

OJ, I have a question about tube diameter for low powered cars. I am swapping a Fiero 2.8V6 into my '72 MGB-GT to replace it's tired (125k mile) original 4-cylinder. The Fiero motor makes about 140hp (net) vs 95hp (gross) on the original engine, which is probably more like 50hp net on my old motor. Anyway, it will get headers and a dual exhaust. Your rule of thumb would suggest that 1.5" is sufficient, but I was thinking 1.75" for some headroom if I want to install a power adder such as a turbo in the future. Do you think that 1.75" would work in this application? Thanks. Dan

[@jonspackman]

Hey OJ, love the videos. I have a 2018 Tahoe with 6.2L and a Whipple supercharger with smog legal tune. I want to upgrade exhaust, but seems no one makes an exhaust with bigger than 3” tubing. Would you build me something cat back? You think 3.5” is worth it for 640hp at tie crank? Thank you

What your thoughts on that upgraded stainless steel you mentioned. And curious to understand the benefits or downsides to upgrading the intake runners to replicate Gold Wheels engine platform. My understanding is taking the air from the plenum gives it that Instant throttle response that you just can’t get otherwise.

What would be the best way to get a deeper exhaust note on a 2.0 L TSI vw? There's millions of prefabbed exhausts that have slight differences in sound, but it seems to me there should be a way to lower the exhaust note while still sounding raspy. What's your opinion?

Would love your thoughts on spintech mufflers. They're kinda like chambered mufflers but use perforated spirals instead. Had them on an monaro (gto) with an LS1, dumped at the diff and my god that sounded incredible.

[@FluidMotorUnion]

Hype. Used them many times and while they do more than many after market options… it’s not better than a high quality straight through design. Think of it like… if a spintech sounds that good imagine what using two super-quiets would be… If there’s a chambered muffler that had a cleaner sound I’d be recommending it.
