Hey everyone,
So I recently installed an BBK O/R X pipe to match up with the Pypes M80 catback that came on the car from the previous owner. It sounds pretty good, but for some reason under acceleration I'm getting a weird fluttering noise. It basically sounds like back when you were a kid and would put a playing card in your rear sprocket on your bike wheel so it would make that distinct noise from hitting the spokes. I'm getting almost that exact sound. So I thought maybe it was an exhaust leak, jacked the car back up, replaced the right side header to X pipe gasket, re tightened every bolt and fitting that connects the X Pipe, took her back out and am still getting the noise. The car isnt driving ant differently, not throwing codes, but that noise wont go away. It's not incredibly loud but under normal acceleration it's quite noticeable. Is this a normal noise from an O/R X or do i possibly have something else wrong?
