Downpipe noise

MCD · 11-14-2012, 07:07 PM

Hi everybody,

Today I had my RaceWerks Downpipe installed on my 328i.
Everything was good, but the car now has a louder noise under hard foot acceleration in low RPM's.
If any of you had the dp installed, did you notice any noise change?! Mine is very noticeable.

Thank you!

That's to be expected. My 2.0 TSI VW CC with a Borla catback became a bit too much when I added a downpipe to it.

Well, what did you expect? If you want no drone go with the Performance exhaust, meaning original dp.

Besides the obvious sound change, how much difference in performance do you feel?
