Catless Downpipe Installed on F80 M3 [VIDEO]

I went down to RaceWerkz the other day and got to check out their new custom downpipe for their F80 M3. It was already installed on the car when I got there so I wasn't able to grab pictures, but I was able to get some video footage from both outside and inside of the car.



As expected the power gains felt very noticeable and it the turbo spool was also very audible. They did a dyno comparison so we'll be able to see how much the power gains actually were, but until we see those charts you can take a listen at how the S55 engine sounds with a downpipe.

7/17 EDIT: I'm seeing everyone weigh in their opinions on the exhast tone so I just wanted to say this. Please note with a catless downpipe the OEM exhaust sound is magnified meaning, yes, there is going to be more rasp which you can clearly hear in the video. Going 12 years back, I remember hearing the same comments about rasp on the E46 M3 when owners first started installing headers to the stock exhaust system, however overtime companies started rolling out with products which basically eliminated rasp. For the early adopters I suggest keeping that in mind. The F8x aftermarket products are still in development and it's too early to have any permanent thoughts on the exhaust sound.

7/19 EDIT: Just stopped by today again and I heard there will be 20 units ready for sale within a couple weeks. Talk to Casey @ RaceWerkz for more info.

9/23 EDIT: RWE F8X M3/M4 Downpipe available! http://f80.bimmerpost.com/forums/sho....php?t=1036990

Hummh, I don't mean to hate on your car, but I'll be honest, I'm not sure I could live with that sound!

Hopefully some exhaust company will find a solution to make this car sound menacing because till now I find it a bit uninspiring! The performance must be addictive though!

+1 I was hoping for a meaner sound once dp's were on the car maybe once the full exhaust is done it will sound better.

Nice! I agree with the others, those DPs and a new exhaust would probably be killer!

Agreed, short of putting a V8 into the thing it's just not going to sound right - you have to figure BMW knew this too and tried everything they could.

This time around, I'm hoping for Eisenmann to come up with best solution - I think the Akra sounds like crap.

God that looks fast!

Sound is disapointing though, hopefully a trick exhaust comes out to enhance it.

Sounds raspy like an E46 M3.

Finding the right exhaust setup/combo will be some work, like the E46. Sounds like someone will have to make a rasp eliminator.

I think those who have already purchased this car or never owned an e92 are just in denial....this sounds like absolute SHIEEEET. It may be amazing in every other way and better than the e92, etc etc....but it still sounds like dog poop.

All that being said, i'll probably be buying one in the next year or so, but i'm not sure i'll be selling my e92 at the same time!
