Just so you guys know....I felt no noticeable power loss with the 3" cat installed. It was $50, I never have to remove it, and it mellowed out the exhaust tone quite a bit. Just the cost of replacing both downpipe gaskets twice is more than $50.91legacyawdturbo wrote:dropdfocus wrote:Cats installed on a car?? Really, you have to do that sorta thing? (yes I'm joking)
PA requires them for visual through out the entire state, but only a handful of cities require the tailpipe sniffer test to pass. So I miss out on the chopping block for that one & the shop I go to lets me slide by simply bringing the stock WRX catted D/P with me to pass the visual. Since it can be swapped out in the matter of 1hr, he figures I could have changed it for the inspection.
Its pretty easy to swap out the whole system, I have to do it every two years at 30 bucks.
Something to think about
