I dont know what size exhaust to go with on my 03 cobra, what size bassani o/r X-pipe should i get? 2.5 or 3 inch? Then from the x pipe to the tail pipes wat size mufflers/Intermediate pipes should i get, 2.5 or 3 inch? In the long run i want to put a different pulley,Idler pullies etc, CAI, and chip it, but its probably not goin to be for a while. Iwant to get the most power but i also want it to be loud and have a really deep rumble. I cant decide and to tell u the truth, i dont really know which size is better, i hope someone can help, Thanx
