weird noise
Hi I was wondering if anyone has experienced this but I recently noticed a weird noise when I accelerate, I don’t know where it is coming from, the noise sounds kind of like a rubbing whirring noise I have the eisenmann race exhaust but I don’t know if its coming from it I can clearly here the exhausts sound then I here the other hissing kind of noise and its driving me crazy I know that my description isn’t that good but has any one experienced anything like this or any suggestions to what it could be thanks- Andrew

I hear you loud and clear. I have an Eisenmann as well but i doubt it's coming from there. Every time i accelerate (especially aggressively) a weird sound comes from below my back seat. It's like metal rubbing on metal. Annoying as hell!!!! I took it to the dealer. I asked them to take my back seat out and check for imperfections but instead, they asked if i had lowered my car. I said yes; having Brabus shocks and springs. After a tour with a technician, their verdict was that the sound was coming from my aftermarket coilovers and that they were either installed improperly or that it's a normal mechanical sound. They refused to touch them as they were aftermarket products. Anyway, i'm kind of living with it. I got used to it. The people who installed the coilovers said that everything looks in place. I don't know...

Wish you were in Los Angeles. We would have met and compared our sounds. Other than that, we may have to deal with it. Every time i have someone in the car i'm asked: "What's that sound"? It's very embarrassing!

The engine itself makes a whirring high pitched noise when you accelerate, maybe that's it? I also have the Eisenmann exhaust and I don't hear anything like that. Maybe there is a small leak where the new muffler is connected? Did you get the resonator cut out?

yea i have a feeling it may be the engine, i dono if it could be a small leak comming from the muffler because i think i would have heard it as soon as they installed the exhaust, i didnt cut the resonator out im still thinking about doing it
