Does the catalytic converter hurt MPG's that much? I am trying to decide between a 5' MBRP Cat back... or 5" turbo back... My biggest concern is come inspection/emission time obviously the cat back is best way to go, but is it worth the $260? or should i spend the extra 200 for TURBO back and get most gains... the turbo back is 5" with a 4" down pipe... Thanks for help here.. trying to buy this system as soon as i can get educated feedback from you pro's out there.
