Hey guys new to the forum and love it! I have a 98 Cobra with stock headers, o/r x-pipe and super 40 flows. For the most part the car sounds good except around 2200-3000 rpm. It has a metal rattling sound and it's awful. Took to muffler shop but no one can give me answers. Prior to the flows car had magnaflow cat back and didn't have this prob. Anyone know what could be causing this?
