Aftermarket Secondary (flex pipe) on Stock Header?
I was wondering if a SSAC or similar secondary would bolt up to my stock header. I am looking at finding a 2", 2.25". 2.5" because my stock flex pipe sounds like its falling apart. I really don't want a header because I don't want my exhaust to sound raspy or have any emission troubles. This is for my b15, but it shouldn't , make a difference.
