Help me decide which exhaust system I should buy

I've been doing some research on a few exhaust systems for my M5 but I don't care about the looks or sound all I care about is horsepower.

I understand that most of you guys have installed different exhaust systems but which one is the best?

Thanks for your help

Unless you go with something completely hiflow (like Kelleners or Nowack - which include new headers and all in some cases) you will be dissapointed with the minimal HP gains. Most of us here have done this upgrade for sound and looks.

Search our archives for "exhaust" and you will find tons of threads on this subject.

Hi

IMO you can forgett about the Hp thing with only exhoust, its all sound.
Unless you do some other mods to your car changeing the exhoust is only a fun factor.

True. Gains with any exhaust less header setup will be minimal. As for systems, I am running the Tubi Style. The quality of the system is top notch. It is a full setup from the catalytic convertors back, whereas most are only rear sections. Maybe I am a BIT bias, as we do sell the Tubi, but we also sell the B&B as well. If you would like to see some pics, please email me. I can also send you some MPEGS as well, although someone may have them hosted already. (Bostonrocket, did you ever get the files I sent you?). Thanks!
