Best BMW M6 Exhaust?! V10 E63 M car gets FMU custom system with insane results!

[@TreatsOnTheStreets]

I usually hate the way these s85 sound when people modify the exhaust but this one actually sounds great. Never heard one like it.

[@jortepap]

Without X pipe it has that bad trumpet-like sound. X pipe makes the tone waay better and more exotic👌

[@Superb_Owl80]

They just sound like an average Chevy i5 with exhaust to me, I’m hoping this video changes my opinion. *edit* well I watched it and meh, still not impressed. Even a ford triton v10 can scream with headers and an x pipe.

[@John_cupra290]

Are you mental😂 there’s not a single American v10 sounds better than even a stock s85🤣🤣. And especially an i5.. vag’s i5 rs engine sounds wicked as i5’s go , but nowhere near as good as a v10s85. Go look what this engine was basically based off of! Obviously it’s not the same engine but it absolutely does have genuine f1 cred.

[@dodgeballdad]

So how much are we talking for this?

[@inaNis_]

That's actually crazy how much better it sounds compared to the resonator/cat delete

an X pipe is always the way to go with these engines. Makes it sound soo much better.

[@gctzx]

This guy presents an S85 as stock that sounds shit, then shows us the smaller mid pipes and highlights the lack of resonators. It's not stock, and the pre-work modifications have made it sound garbage. A real stock S85 sounds great, just a little quiet.

[@scottsracing]

The biggest restriction in the S85 is the top end of the motor. The factory plenums are too small and are really thick, muting the ITBs. Most people looked to the exhaust, and that's how so many of these cars ended up with hacked up systems. One of these days I'd love to hear an S85 car with both the full FMU treatment AND a full CSL spec induction system from Infinity Design. That would be peak E60 M5.

[@Alfonso-mh1np]

On the uneven firing v10 you need to make unequal length exhaust like the secret weapon exhaust in brazil and it makes it sound like an f1 and more even sounding because they make one pipe longer before it reaches the x pipe and that fixes the uneven sound of the firing order. You should look into it there's also a calculation you can do to delay the exhaust pulse on one bank by making it longer and the calculation will tell you how much longer it needs to be than the other one to reach an even 72 degrees in between each fire

[@inaNis_]

@@Alfonso-mh1np there’s a great David Vizard video on just this topic

[@Alfonso-mh1np]

@inaNis_ can you send it to me please or at least the video title

[@damascus-ut1ee]

It will always be alternating between 90° and 54° and “odd firing” is commonly misunderstood on V10s. An odd firing V10 still alternates between each bank without firing twice on each bank. So an “uneven” firing order technically still is “even” firing when talking about banks- but only on V10s. On a V8 crankshaft you must have a flat plane to even fire. As far as the exhaust you’re talking about, adding a section of length to one side of the bank will not make it 72° of firing order. It still fires the same in the engine. All you’re doing with that is shifting ALL exhaust pulses on that bank an EQUAL amount of phasing. Which means it will affectively not change anything too much. Sure you might be able to phase one cylinder on that bank to sound like a 72° firing from the other bank, but the next one can’t be 72° because you’re now at the 90 or 54 angle on the other bank.

@@damascus-ut1ee What he meant is by making certain pipes longer and shorter so they all reach the collector at the same time.

[@E63s_Scott]

I stuck long tube headers on my m156 6.2 c63, no cats into the stock resonator and stock muffler, it was the best sounding car I’ve ever heard, zero and I mean zero drone and it was dead silent under 2.5k cruising off cam, yet above 3k it was mental easily 130db + loud, with added aggressive downshift added in my tune, it had the most amazing ear piercing snap, and amazing intake noise through the headers, as they where thin walled, amazing. Now I have an E63s with down pipes and valves fully opened sounds mega for a turbo smaller displacement motor not not quite that 6.2!

[@FWRXSTER]

Ask an enthusiast: For an immersive driving experience, would you rather drive a silent Model S Plaid (fast) or an S2000 with a full exhaust (objectively, slower than the Plaid)? I think most would go for the S2000. Speed isn’t always everything. Sound and engagement can do a lot more for the experience of operating a vehicle than speed alone. Thanks for the vid OJ

[@joeymcquilkin3670]

Strongly disagree Meistershaft / headers / no cats is where it’s at I’ve been in and around so many of these cars and the M5’s, they sound insane the louder they are and really makes the V10 scream

[@lockingdiff]

As the owner of a few S85 cars in my day, the only worthwhile exhaust mod for these cars is a muffler delete. No drone, perfect sound, no buzz or rasp, and 90lbs in weight saved. It basically sounds identical to the final result in this video. And for some reason, on the 2006/07 cars, they pop and bang. Here's a video of one in NYC kzbin.info/www/bejne/rGS5nX6PpLJ3hdk

[@CL9k24a3]

That was truly special. Fiy there is guy making Z pipe instead of X pipe. Somethimg you might be interested in.

[@zhaoyangxie]

Definitely a very clean sound without rasp. Nice work, but would be cool if it was higher pitched

[@EightyFiveHundred]

Nice! I remember KenL’s s85 FMU build from back in the day on m5board. Fast forward 15 years and I’m still running my s85, now with 197,000+ miles of track days, kid/dog hauling, road trips, with lots of maintenance. Off the shelf doesn’t work for my needs. After much trial and trial and trial and errors, finally settled on a custom full titanium resonator, x-pipe, and exhaust. The weight savings over SS is worth it alone. Still tweaking things with my fabricator as he thinks there is room for improvement. Nonetheless, love that you’re giving the s85 owners some love. If I was not in SoCal, FMU would have my business.

[@weheretowatchandcomment]

Can you run down the maintenance on yours? I’m looking to buy one and want it to go further than that. It’s amazing you got it that high in mileage

Calling you out, because this seems a bit bla bla bla. I have had multiple different exhaust setups on my E60 M5, and they all sounded great (never heard anyone complain about the sound of an S85). 1. Stock system + Eissenmann Race mufflers: sounded clean, deep, little rasp and no drone 2. Stock cats + 2 straight pipes + no drone mufflers. Sounded extremely loud, full, little rasp. Almost like two five-cylinders next to each other. > sounded the most like your setup. 3. Stock cats + X-pipe + Valved no drone mufflers. This gave me the highest volume and pitch. Almost an F1-like sound. Loved it. 4. Stock system with a muffler delete: bang for the buck the best option. Stock sound but with more volume, rasp and no drone.

[@ottomobili2575]

There are a couple crazy videos on KZbin from 10-15 years ago of a couple guys in Brazil who cut the pipes off an E60 M5 and took the car up to 200mph - sounds glorious!

[@clinttube]

Watched with great interest having recently picked up a 6-speed M6 like this as my first BMW. I think you're right about the times changing and people realizing driving experience and uniqueness will increasingly beat out raw speed. Hence why I went with the 6-speed which is appreciably slower than the SMG (but way more reliable). I like the SMG too though people hate on it but it suites the car. One of the few things I want to do to mine is exhaust and have been watching your channel. Really would like more videos of this system under normal load/in-car both cruising and full throttle. Also, that "stock" system is not stock at all as you mentioned I think the stock sound is pretty darn good just way too quiet/muted. Maybe people were cheap historically but I haven't considered (nor even seen until this video) a single system below $2,500 new; more like $4k range. Personally I want something that raises the volume and tone but isn't TOO obnoxious or insane around town that I couldn't take my boss or wife in it. Whether that's valved or what I'm still researching but I would definitely be interested in a system like this.

[@Zcypot]

I never bought pre built exhaust, nothing wrong with them. I spent so much testing different resonators and mufflers until i found the setup I like. Im sure it could sound better though.

[@2WheelsSometimes1]

Got a question about the x pipe setup. On this model, you have two short bends from the header to the x pipe. The headers look like they're merging at 45deg, is there a reason why you didn't place the x pipe directly off of the headers? This exhaust sounds amazing, great work done by your whole team.

[@ChurchAutoTest]

Helluva a lot better than any BMW V10 I've heard. Still not awesome or as exotic sounding as you'd want a V10, but if you're working with stock valve timing events you can only do so much.

[@Jimmy_Bee]

You need stepped equal length headers, the exhaust sound all comes from the sound waves and how you control them and stepped headers create more waves. Right now it just sounds like you’ve basically straight piped it, “refined?” It’s freaking absurdly loud. 😂

[@eQuASiANXane]

It instantly reminds me of the W204 C63 with the current tips, sounds great too.

[@pugs1377]

Sounds perfect! I want to see you guys do an n63tu, not an s63. The exhaust manifold difference makes big difference in sound I think. I just hacked off the muffler on mine and straight piped it axel back to stock tips with two 90°s on each side. I plan on doing an x pipe when I get time. I have a vid of my f15 x5 50i reving if you want to check it out.

[@e.v.a.l.s]

no they don't. anything from honda that actually runs sounds like total shit. you can't try to counter sound is subjective in the same breath of anything from honda even sounding semi okay-turbo or not. the only tip for a honda k series is the same as any other honda engine. melt it

[@papapetad]

@@e.v.a.l.s My most memorable turbo k sound clip is from a hoonigan drag race. It was a high power thing with external wastegate and sounded great. Many moons ago I saw a 4g prelude with the H22 and it had a loopback muffler at the back. It really transformed the sound, making it much deeper and smoother. I was wondering if anything of the sort was tested on the k series. Also looking at fluid's use of megaphones and a step down to the rear mufflers on this...curious to see how they'd tackle a k exhaust. Then again, they've said it before and in this video too: biggest influence is valve/port design. Only so much you can fix with the exhaust.
