catback exhaust systems/downpipes
 

Need some feedback on catback exhaust system...looking for something that will give me a good output from engine and a clean sound.
While im on the topic need some info on straight piping and downpipes all high flow and im looking into a 3" exhaust tip...i know the basics but im wonderin what other dsm'ers are runnin in their cars and what would be recommended for an eclipse 99 turbo...i already have an intake, BOV, and MBC.
P.S. how do i make sure that everything fits correctly...should i buy the cat-back exhaust and downpipes from same makers? Thanx
