What do you recommend for an x-pipe with catalytic converters? I want to keep my car street legal, because I've heard its a total pain in the a** to always be changing them. Also, what would you recommend for an axel-back or cat-back system? I've been looking at the Flowmaster American Thunders and the Boomtubes (but I've heard Boomtubes suck
).
I don't want the car to be extremely loud, and I want the car to be street legal. I'm looking more for a performance increase than a sound increase. I drive a 2008 automatic GT.
(I know exhaust doesn't give a huge boost on its own, lol
)
Links and personal experience would be wonderful!
Thanks a ton!
