Wsup guys, doing some research and I was wondering if anybody here has done a custom exhaust, or if anybody has done a straight pipe... Ive been watching videos of exhaust clips and I havnt heard anything too crazy or too loud...Ive got my E55 with no cats, no res, and eisenman race mufflers, and My S63 has no cats/res...my bmw 650 is straight piped... So you guys can get an Idea of what I mean by somthing crazy and loud... this guy that lives down the street from me had straight pipes on his 997TT, I never got to hear it, but he said he couldnt even speak on the phone with the windows up


is this straight piped?

I ve custom removed the cats from the evoms exhaust.You won't need the straight pipe.Now its perfact.When the car standing or under normal street drive,the sound just like what it was when the cats on.but once you rev it over 3000rpm it turns to crazy and you could hear anything else just the super exhaust sound..
