What are you running for exhaust?
have went through a few
did magna flow catback with stock everything else (got for $300, sold instantly for $300) sounded great would've kept if the stainless was better quality, could see a year of new england already was taking its toll on it, 304 exhausts i've had have looked better after 5+ winters.
then picked up borla uel, perrin overpipe, perrin 3" frontpipe, perrin 3" catback in a package steal.
with everything it sounded amazing as long as you were not anywhere near civilization.
got sick of the noise, removed the header, much quieter but a bit of in cabin resonation at light throttle passing/uphill on highway
pulled the catback, now just on overpipe and front pipe, bit deeper and louder when you get on it, otherwise quiet like stock.
sold the header and catback for nearly all what the whole package cost.
now i'm starting to think about the tomei 60s, which i know will be a terrible idea. so should probably find some tips before I get stupid or find another used deal.
that and i've seen variations in price on the corsa (like apr rcs) of anywhere from about 1200 to 800ish shipped. thats kinda tempting too.
