I have a 04 cobra...trying to find the right mid pipe for my car...I have Kook LT and catback system...all pulleys,
Mass air, cold air intake, diablo programmer, think injectors are stock(blue) not sure what else just bought the car a month ago...it's pushing right at 15psi..right now it has a 2 1/2" x pipe with cats..however car is lowered and cats are dragging causing exhaust leaks..my headers at the collector are 2 1/2" with a 3" catback system..should I run a 2 1/2" or 3" mid pipe and if I don't run any cats will I still have enough back pressure?? 2 1/2 or 3" cats or no cats??
