Don’t take this as criticism, take it as feedback. Merging two flows right before a bend/fitting isn’t taking advantage of the Coandă effect… as an HVAC guy i’m always trying to maximize laminar flow, before any bend or change in direction i utilize a straight section as long as i can to maximize the airs desire to follow along the surface; doing so balanced out and quieted down every system i’ve installed. Everything else in the video made perfect sense
32:39 tell me that isn't the cleanest sounding s54... with a fmu rear section it will end up being perfect, but even with the stock rear section it sounds SO clean.
I heard a loud, raspy sound in the distance and immediately assumed it was a 4-cylinder. To my surprise, it turned out to be a BMW G80 with a valvetronic exhaust. If I had a six-figure car that sounded like that, I'd be pretty disappointed. The exhaust system that OJ and Cody made, on the other hand, sounds fantastic-they should be proud of their work!
@@gabegabes6419no it’s not. It sounds like a broken trumpet. There’s a reason why the Inline 6s from the 90s sound superior to today’s because they weren’t raspy.
@@AllOutNoobHater Ok I can agree with that! I meant in general if an exhaust sounds good, the titanium version sounds a lil more exotic, so yeah I get what you guys were trying to point out now, that specific brand sounds like shit?
The biggest issue is that it’s a Twin Turbo setup and to get a TT Straight 6 to sound good is borderline impossible because of the way the headers and manifold have to be set up since exhaust manifold is on once side. It’s difficult to get the equal length effect. While the exhaust u made sounds great in my opinion, the only way to get it really good, is go single turbo, equal length, tubular headers IMO
@@MistaaFrostythe TT V6 in the Giulia QV and in the B5 S4s sound good too (tbh maybe the only V6s besides the Busso that I actually like the sound of).
One day I’ll bring my car to FMU after I finish working on it this winter. I honestly believe it’ll benefit greatly from an exhaust system built by these guys.
32:44 sounds like a more subtle valvetronic g80 exhaust, just more refined. open up that rear section and its perfect. 33:30 LMAO you read my mind it seems. literally a v tronic system... 33:50 compared to their own videos i am amazed at how raspy it sounds... 34:55 it's always amazing how clean you get the sound to be. like you say, the rear section is going to be the cherry on top. love the megaphone science and I have to say, the quality and content in the videos has been amazing as of late. :)
Lovely, I have a G87 and if I were to do an exhaust I think I would go with just the midsection like you showed here (I wiuld say I’d go with this exact one but it’s for a G80 so won’t fit. No rasp, not too loud, big power gain. Great stuff 🔥
The 2 into 1 on these s58’s is the key to having the twin turbo set up sound good. I had a Vrsf exhaust on my n54 335i which is a 2 into 1 set up and it sounded insanely good on my twin turbo set up. This starting midpipe sounds really good. Stoked to see what y’all come up with
I'd definitely take my g80 to you guys if I wasn't across the country from y'all. Exhaust systems for the G80 is like walking in a mine field. I have spent way more hours than I'd like searching for something that doesn't have rasp. It shouldn't be this difficult!
This was a really interesting video. Great work. Having been watching your videos for a few years now thanks to Alex at LSC, I've noticed your confidence in doing videos has really gone up. You are a lot more fluid (pun intended) at your narration. Great work!!
If a straight six doesn't have a howl to it it just isn't worth it. I remember the Nissan L28, the engine in the 280Z and ZX, that one sounded wonderful. The Jaguar 3.8 and 4.2 liter twin cam six is another, the original BMW M5 was a beast to the ears. A well tuned Nissan RB or Toyota JZ....well, ya know.
Took me a long time to figure it out, but imo, best inline six sound is simple in theory. 24v, 8.5:1 compression, decent cams (230 degree or thereabouts, more is fine), cast manifold, big single turbo, vibrant straight thru resonator, and finally magnaflow straight thru muffler.
2 into 1 has always been the way for inline 6 engines. The Japanese solved this problem back in the 90’s when they did single exit exhausts for the 2JZGTE and RB26. Figure out a way to make that same single exit sound from dual exit to keep the new aesthetic or we’ll just have to get aftermarket diffuser companies to close up the right side of the bumper and just do single out. It’s as simple as that. I don’t hear anyone complaining “real” old school Supras or Skylines don’t sound good.
YES!!! I’ve been waiting for the G80 S58 exhaust video… I haven’t bought a midpipe or anything yet holding my fingers crossed until you guys did one! :)
I wish you guys were located in my city. Three exhaust shops later and my car still turns into an earsplitting high pitched drone at 4500 rpms. 3.8L, 6 cyl,Turbo with 3" dual exhaust, no cats, just mufflers.
single midpipe is the way. I hope you’ll get to work on an F80 someday. A single pipe all the way back to a muffler is something that should be considered on the S55 and S58. There’s a few European companies that nailed the sound this way and im trying to replicate it with my dinan muffler
Huge improvement, here in the UK our g8x ‘s sound even worse as we have a gpf fitted . Would have been interesting to hear it with the valves shut but really like the sound
Sadly, the move towards being "as obnoxiously loud as possible" is the goal for many in the car world these days, it's no surprise that makers are leaving rasp, decibels and pops in their systems and tunes. Not surprising, its partly due to youth, partly due to just needing to stick out more in order to be seen and partly due to living in a digital world where "through a mic and speakers" is the only way most people experience your build. I personally prefer smooth, subtle and restrained but we all had our younger days when chopping everything off and setting off car alarms was the goal!
Quite impressive with the numbers they showed on the dyno with their custom section. Sheesh! I’d take the more refined and clean sound with the 30whp+ over the V tronic system lmao.
@@pandaboi57 That's not what is shown on the dynograph. It shows a STOCK vehicle versus a car with their V2 midpipe AND a front mount intake and open/closed muffler valves. That 30hp gain is from an intake and the exhaust changes. That really seems deceptive.
You need stepped headers (smaller primary pipe to larger, halfway to collector), which will basically introduce a sound wave at the step that doubles the resonance and makes the exotic sound
You need vibrational analysis and gas flow simulation to actually go into a project like this with any direction. Doing this by just eyeballing it is the equivalent of tuning a piano by the tension in the wire and no sound.
The biggest restriction, will always be the smallest hole. No matter how many times you go from smaller to bigger, the smaller will always be a restriction.
@ haha I never thought that someone will want to pin my comment 🤣 yeah but driftworks did pretty good job with exhaust don’t u think ? I hate those ridiculous burbles, and tin can sound
Bout 18 minutes in and I gotta agree with the guy about those merges. They look like they were made by punching a hole in a U-shaped pipe even though I can clearly see the triangle weld, that's still what that look like and apparently how they operate. Making a proper merge such as a collector-style merge would help those hot spots for sure. *EDIT:* After watching the rest and doing my own math, I wonder if you guys could've fit a dual 3.25 into single 4.5 in there. That should be good for about 850-900hp of flow according to some more accurate rules of thumb out there.
How much backpressure does that megaphone produce? Because that is what will happen with that shape. On 2 stroke it literally has the function to send soundwaves back to push gas mixture back into the cilinder.
Please try the same approach with the S63TU4 because I’m confident that with your expertise, you can extract more performance than Valvetronic Designs, who claim to make the best exhaust for the M5 F90. The S63TU4 has a beautiful scream, but most exhaust systems sound too high-pitched.
I’d love for you guys to do a 90’s Lexus LS400. I’m currently planning an exhaust build/layout and would love to see what you guys would come up with!!
What you guys did is way better than the titanium system. I'm normally a big fan of titanium systems but, that snappy/rasp that it produces doesn't suit the sound of that platform, in my opinion. It's all a personal opinion, of course, but they produce a low-end grunty sound and titanium sounds better on a snappy high rev screamer. It's a very basic description, and it doesn't actually correlate with the engines characteristics, just the sound character they make.
You guys need to sort out the S55 engine. These cars are alot more attainable now due to their age, so potentially alot more popular in terms of customers.
Sir Awesome why of Thinking. I have a 2017 Porsche Cayenne 3.6l VR6. That I don’t have Tons of money. And love the Stages Exhaust. Like this Build. I want to get rid of the Heavy Rear Muffler. And love to see what you Would Design after the First Resonator . Thanks. Gory
Yes I second that. And matching down pipes and rear section that reuse factory flaps so you can keep control like factory. Well one can dream I guess!!! 😅
That came out great, I wonder how the megaphone mixed with a custom y pipe would help hp/torque increase on a VQ35HR or VQ37VHR. Lots of people have struggled with making them sound good. I love how mine sounds currently but would like to see what you guys can do with the y pipe/y pipe back section.
This sounds really awesome on video, so great work so far! Would love to see the whole system aswell. Question. As a G87 M2 owner, will you also do something for that model?
This is ok for a cheap fix. Doing it properly would involve a single turbo conversion of some sort, which is about the same cost as a high end bolt on exhaust system.
Seriously make a video with a 2009 Crown Victoria. I love the tried and true V8 DOHC. I'm going to replace the H-Pipe with an X-Pipe into Flowmaster Flow FX Muffler. But keeping all 4 Cats. Got the parts.

I know you focus on High End cars. But the fewest own a High End car.
41:36. I have never seen a 7 or 8 inch exhaust on an F1. I thought the ideal volume - length of a merge (for max HP) is in-part relative to the frequency of the shock waves from both exhausts. I also thought that a megaphone produces a re-bounding negative wave (back towards the engine).
And f1 exhaust system doesn’t have to navigate the length of a passenger vehicle. Which is exactly why say- it’s a hot rodder rule of thumb that gets you close to knowing if in the 15 or so feet of distance- with all the bends that it inevitably will be in the system- you are leaving flow on the table… again WITHIN THE CONSTRAINTS of the car. If you can’t physically fit 7 inch, you split to dual 3.5s. Sometimes you have to leave flow on the table because it won’t clear what you need to clear. RULE OF THUMB- lol! Again length of merge calculations are fine… if you can physically fit it. We’re using the megaphone for the pressure wave pulse split… for SOUND. If we were tuning a megaphone for scavenging… that takes a whole bunch more work that is never worth it the cost and time of development on a street car for the possible gains. Especially considering that when Megaphones are used for power, they are dialed into a specific RPM, and can even be course specific for the engineer/racer! Bruh, we’re a shop that’s know for making great sounding exhausts that don’t lose power on street cars…and I’m just trying to show you guys how we balance those things with our 16 years of practical experience.
Go back to alumanized steel. Stainless and ti have their places but for tone you need to consider a metals natural resonance frequencies. Aluminum will give it more bass and less tinny quality and I think that’s what a lot of ppl see yearning for for s54 and s58. Worth a try, but I think you’ll hear a difference you like. .02
Bravo!!! I'm building an exhaust system for an NA BMW I6 (M54). It was great to get a sneak peek into your recipe for the straight 6! Awesome execution!! I'm excited for more! ❤
Buddy has a zhp , the cheat code for his car is e36 m3 headers to y pipe to a single catback not twin using the spec 46 mahnorflow system with a magnaflow cat before the muffler sounds literally perfect and crisp no rasp
There's a system like that already from Canadian guys. Yonaka Motorsports. Y merge as close to the engine as possible. Best non-M E46 exhaust IMO. Sadly it's not legal in Europe, no ECE/TUV certificate. I would buy it in a heartbeat if it was legal in Europe.
@@Falco_e46 You can ask your custom guys to build you something similar by showing them a photo. Rule of thumb is Y close to the headers for max power and then 3 inch single pipe for M54 engines. Anything larger than 3 inch loses too much gas velocity. Anything smaller presents a choke point.
Great Video! I want to have a local shop build a system for my B58 540i and add a megaphone, what mufflers and/or resonators do you recommend to prevent drone?
Keeping the stock rear exhaust gives you the opportunity to say "It's stock oficer.." XD The amazement on dude face after seeing what you acomplished says a lot You did an amazing job, but between us.. the bars with their "design" didn't challenged you at all In my opinion, the only challenge for you was to fit under the car the ingredients that you know will get most out of the situation Rasp is loud, but grinds the eardrums
no burble sounds so good. you can finally hear the exhaust tone without it being ruined with pops.
Yeah honestly, shit sounds so whack
burbles are so overrated
Only 17 year old kids like burble tunes lol
Burbles on lowest setting is perfect
@ no it’s gay

They did already. I have an E46 M3 with a FMU full custom exhaust and it's one of the best sounding exhausts that I've ever heard.

Valvetronic titanium exhausts are overhyped, raspy crap for fboys.
Totally agree! They claim to make the best exhausts for the S58 and S63TU4, but most of their setups just end up sounding too high-pitched and raspy.

I know you focus on High End cars.
But the fewest own a High End car.
N55 the best sounding bmw engine when its stock with catless dp
41:36. I have never seen a 7 or 8 inch exhaust on an F1. I thought the ideal volume - length of a merge (for max HP) is in-part relative to the frequency of the shock waves from both exhausts. I also thought that a megaphone produces a re-bounding negative wave (back towards the engine).
And f1 exhaust system doesn’t have to navigate the length of a passenger vehicle. Which is exactly why say- it’s a hot rodder rule of thumb that gets you close to knowing if in the 15 or so feet of distance- with all the bends that it inevitably will be in the system- you are leaving flow on the table… again WITHIN THE CONSTRAINTS of the car. If you can’t physically fit 7 inch, you split to dual 3.5s. Sometimes you have to leave flow on the table because it won’t clear what you need to clear. RULE OF THUMB- lol!
Again length of merge calculations are fine… if you can physically fit it.
We’re using the megaphone for the pressure wave pulse split… for SOUND. If we were tuning a megaphone for scavenging… that takes a whole bunch more work that is never worth it the cost and time of development on a street car for the possible gains. Especially considering that when Megaphones are used for power, they are dialed into a specific RPM, and can even be course specific for the engineer/racer!
Bruh, we’re a shop that’s know for making great sounding exhausts that don’t lose power on street cars…and I’m just trying to show you guys how we balance those things with our 16 years of practical experience.
When will this exhaust be available to the public?
we are working on it. email us your info all@fluidmotorunion.com to be put on the list
Go back to alumanized steel. Stainless and ti have their places but for tone you need to consider a metals natural resonance frequencies. Aluminum will give it more bass and less tinny quality and I think that’s what a lot of ppl see yearning for for s54 and s58. Worth a try, but I think you’ll hear a difference you like. .02
Sounds mint, surely you can have a go at fixing the sound on the s55 next?
Need a S54 video! Would love to see 6 to 1 equal length headers on a full custom exhaust.
Have you done exhausts on 4 cylinder engines? Seeing a flat four Porsche would be interesting
Single turbo manifold = Fixed 🤣
deadass
Love to hear how you’d make a v6 sound better
Bravo!!! I'm building an exhaust system for an NA BMW I6 (M54). It was great to get a sneak peek into your recipe for the straight 6! Awesome execution!! I'm excited for more! ❤
Buddy has a zhp , the cheat code for his car is e36 m3 headers to y pipe to a single catback not twin using the spec 46 mahnorflow system with a magnaflow cat before the muffler sounds literally perfect and crisp no rasp
There's a system like that already from Canadian guys. Yonaka Motorsports. Y merge as close to the engine as possible. Best non-M E46 exhaust IMO. Sadly it's not legal in Europe, no ECE/TUV certificate. I would buy it in a heartbeat if it was legal in Europe.
@@idokwatcher2062wow… i am looking to get a custom exhaust on my e46… thanks for mentioning this one haha
@@Falco_e46 You can ask your custom guys to build you something similar by showing them a photo. Rule of thumb is Y close to the headers for max power and then 3 inch single pipe for M54 engines. Anything larger than 3 inch loses too much gas velocity. Anything smaller presents a choke point.
@ i‘d go 2.5“. Slightly higher pitch, and 2.5“ is really easily enough for 192hp
You fixed the rasp. Paper noise. Much better.
I'd like to see what you could do with a ct4v Blackwing.
Same!
Great Video!
I want to have a local shop build a system for my B58 540i and add a megaphone, what mufflers and/or resonators do you recommend to prevent drone?
Would love to see a non twin turbo line line 6 like the n55
When can I buy a FMU midpipe for my g87?
hit us up all@fluidmotorunion.com
Now do S55. We’ve waited so long and got skipped
Is this exhaust going to be mass produced and sold by IRL?
OJ in his shmedium shirt talking about fitting things into tight places.
Keeping the stock rear exhaust gives you the opportunity to say "It's stock oficer.." XD
The amazement on dude face after seeing what you acomplished says a lot
You did an amazing job, but between us.. the bars with their "design" didn't challenged you at all
In my opinion, the only challenge for you was to fit under the car the ingredients that you know will get most out of the situation
Rasp is loud, but grinds the eardrums
Mein Gott BMW that paddle click is flippin *_EGREGIOUS_* 😂
I wonder if you guys can do a new generation super WRX would definitely be curious with what sound you guys could get out of those
