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

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

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 Ай бұрын

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.

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.

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

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.

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

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.

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.

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.

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.
