ok its not a real problem but now its getting annoying! every time i shift gears i hear like this popping noise coming from my exhaust even at low rpms. Sometimes i doesnt happen, keep in mind i have 2.25 ehaust piping and a aftermarket catback could it be backpressure problems and will it harm my hp? ur advice is apreciated-thnx

Nah my car just has a stock header. i think to go catless u just replace the catalytic converter with a piece of exhaust pipe.

Then you would still have a cat, because there is one on the exhaust manifold as well as along the piping.

I have this happen every once in a while with my exhaust setup, and I have both cats still! The last time was a few months ago, but I remember when I heard the pop from the exhaust, I felt it in the pedals as well. Very strange, but it doesn't bother me. I just love the rumble!
