ok so i just recently picked up a 03 cobra with 30xxx miles an is bone stock except for a mgw shifter and a 3" MAC catback... so my questions are, 1. is there a 3" o/r x pipe that will bolt up to the stock manifolds? 2. if i put the o/r x pipe on do i need to do a tune with it? is it going to cause damage? i had a 07 gt before put the x pipe on and didnt tune an ran just fine. 3.what x pipe combo sounds really good with the 3" mac setup thanks!
