BMW Performance Exhaust too quiet?
hey guys recently i just installed bmw performance exhaust it's been 3 days but i still think it's too quiet?
in cabin with windows rolled up i hear no exhaust noise as if it is stock. when i have my windows rolled down barely noticeable as if it's not even there. after taking it to high RPMs the intake sound much louder is it supposed to be like that? ive heard great things about the exhaust but it's barely noticeable comparing to OEM for non-turbo btw. help? |

Funny, this is the exact reason why I'd even consider the BMW Performance exhaust. If you want turn-your-head loud, it's not the one to get.
Just drive about 4K RPM all the time, and I'm sure it's loud enough.

Give it some more time to be broken in man, it's too early to tell if it's too quiet IMO.

I assume you installed the full system incl the resonator delete?
I love mine, just perfect for my taste. Quiet when and where you want it to be, growling when you feel "spirited". Love it to death, good combo with the perf. intake.

Had mine for a week now - too early to decide if it's perfect...but definitely better than stock. I like the fact I can go on long weekly family trips to hockey games without any intrusive drone in the cabin
(but you can hear a difference, especially some low-end grunt accelerating from 2-3K in 5/6th) Cold starts can absolutely be heard in the cabin Blips for rev-match can be heard in the cabin, and by my neighbours Haven't decided if I like the "burbling" / small backfires with engine breaking...may be a little over the top. Hoping to meet someone with the perf intake to see what subtle effect that has. Anyway - no regrets for the $. |

Had mine on since June and it's just right as far as sound goes. I can really hear it in the cabin unless my windows are rolled down, which is what's great about it. The exhaust does sound great from the outside. Stand outside and have a friend drive your car around, you'll be in for a suprise.

BMW "Performance" exhaust sucks!
Agree with OP. The BMW Performance exhaust sucks. (Mental note: revise review on my website. Wrote it with optimistic dreams when still convinced it would eventually sound good after break-in.)
Had mine for 3 weeks now, well over 1000 miles, and it's WAY too quiet for a *%$#@%! $1,500 system. Idle? Can't hear a thing. Can't feel a thing. Casual driving with windows closed? Can't hear a thing. Casual driving with all windows wide open? Can vaguely hear a fart pipe (is that the Civic next to me?). Full WOT with windows closed? Can vaguely hear a fart pipe (is that the Civic next to me?) Full WOT with all windows wide open? Can hear something. Is that me? ...but after paying $1,500 for an exhaust system, I shouldn't have to go to full throttle with all windows open to even hear it. This afternoon I gave my boss a ride to the airport (it was my little way of saying "We'll all miss you! Have a great time for the next week at the conference!"). I told him I'd modified the intake and exhaust and he didn't believe me. I was honestly embarassed. Yet somehow the BMW Performance exhaust gets rave reviews over and over. WTF??? I'm not expecting the car to sound like a Chevy 350 with Flowmasters, but still--WTF??? Given that I'm an ex-Corvette driver who likes the sound of open headers, can anyone suggest an alternative that's perhaps "too loud" by the average BMW "enthusiast" standards? Muffler delete? What do I have to lose, at this point...? The BMW Performance exhaust might be considered an "aggressive" note to someone in a nursing home, but not to anyone who's ever described their ideal Friday night as test 'n tune at the local dragstrip. What a friggin joke. Pissed away cash.

what! didn't u have an Eisemann and just sell it because u said it was to loud... not that much difference / slight difference. look at Andy@LTBMW video with Eisemann and BMW Performance comparison. They say it takes a couple of weeks for the BMW Exhaust to break-in. sound wise. Mine got a bit full'r / louder. Personally I like the gurggle and pop.

There is a tread somewhere that talk about removing (or disconnecting) the "attenuator" (it is like loudness control) located in the trunk. Perhaps the shop did not disconnect that. You may want to advise them of this. I have the performance exhaust and I find it too loud at time. Windows down, I clearly can hear. As a matter of fact, since I had it installed, people who knew my car from before, tell me that there is "something wrong" with my muffler. Another possibility is your engine. I am not sure if the 328 would have as much response (noise/loudness) as the 335's turbos. In any case, I suggest you speak to the shop about this. I will post the link to the thread that talks about the "attenuator" if I find it. good luck!

I suggest you and the OP get to an audiologist and have your hearing checked. Perhaps too much ear wax buildup.
But seriously, I've had the Performance exhaust on my 328i for about three weeks now and it's quite noticeable. There must be some problem with your equipment or your installation if you're not hearing any difference. |

I have it on my car and the sound is very noticable to anyone outside the car and with my windows down I can clearly hear it. What I love about the exhaust is that it's not intrusive, so with my windows up I can have a converstion and not have it drowned out by the exhaust note. I'm telling you stand outside and have a friend do a roll by in your car. You will love what you hear. |
