thanks in advance

I think your problem is within your bbk x pipe. i know from experience because i had the same set up with slp resonators and i heard the noise almost like metal hitting metal. so i changed to a magnaflow cat back and it sounded even worse. i found out it was the amount of air in the x pipe didnt translate to the amount of air leaving your car... very common problem. im pretty sure a tune would help
