I have the x-pipe and the dinan exhaust...the sound at high rpm has changed to a loud clang...my tuner thinks that the cats may have been damaged during install and that there maybe loose ceramic pieces rattling around...sooo...on monday, after the catalytic converters are replaced, if the sound is the same, then i will take the x-pipe off and sell it!
