Short vid of my GPower - The Unofficial BMW M5 Messageboard (m5board.com)

Played with my new dig camera this afternoon and took this video of my GPower exhaust. Best if listened with subwoofer/speaker setup or headphones at a minimum or the deep tones and bass will be heard as rasp that is just nonexistent in person.

Enjoy!

GDA, Sounds nice...I'm still looking into exhausts for my car. Couple of questions, Is your exhaust cat back?, Did you eliminate the resonator? Is it muffler only? How long did it take to get? How much$ ? I'm leaning toward Eisenmann, did you check into them? Thanks.

This is the exhaust that was installed by the previous german owner. Its the TUV (quieter) version with resonators in the tips. Its full cat back and has a resonator. I am going to replace with GPower medium sound version with straight tips. I have not pulled the trigger as I am waiting for more info on front/rear custom stress bars (shock towers) and possible custom exhaust without the resonator (straight pipes from cat to rear silencer).

Everything I'ver heard indicates Kelleners and GPower outsources their manufacturing to Eisenmann in Germany so sound differences between any of these 3 is probably very small.

Are you going to source through Eisenhaus in Chicago?

just installed eisenman race exhaust with no resonator and a high flow cat from kinneys exhaust in hurst tx. they ran 3 inch pipe from headers to cat and 21/2 from cat to muffler and it is very loud but sounds awesome. it made a noticable performance diffrence but you cant hear the engine anymore. great performance but beware of the noise.

Christx, you have the set-up that I am thinking about. Is your car so loud that you can only hear the exhaust from inside the car? I like the S38 engine noise and I would be bummed if I could only hear a booming exhaust inside the car. Maybe I'll take a step back from the race muffler. I think I'm going to talk to the guys at Eisenhaus.
