BBK X-pipe and flows = crap
VRS X-pipe and flows = badass
For some reason BBKs X-pipe makes the worst metal clanging resonating sound know to man when used with flowmasters. I ran one on my car for around a month. I originally had two chamber flows dumped, it sounded like complete crap with BBK X, I then went to american thunder cat back still sounded like crap. Took BBK X off and bought a BBK H pipe, I then sold the H pipe to my friend because it did not fit my exhaust manifolds any more after the engine work. I then bought a VRS X-pipe and couldn't be happier. It is very loud though so I hope you don't mind pissing off your neighbors when you wake them up.
