who in here or on here is running a b series, test pipe, and a magnaflow catback....
does it sound like ***? mine does i cant figure it out two resonators (one in the test pipe) and it still sounds like a friggin z6 open header

 

check for cracks and bad gaskets

 

ok heres another stupid question its got a header it was on the car when i bought it 4-1 and the collector is kinda small (no money thought about it) deff. not JDM 2.5" the test pipe is 2.25" and the exhaust is too. i think the donut is bad so what size do you think it is with out me lugging the digital out there. the test pipe really doesnt fit the collector like fill it up so what do yall think i should do
