Alright guys I'm trying to find a company that makes a x pipe for my car-1993 coupe w/ 351 and C4 transmission. The headers are BBK Shortys. I was just wondering if any one makes an x pipe for the auto transmission, if so would the 5.0 be different than a 5.8? I ran a x pipe on my old 94 GT auto, but I had to be the x and make everything else it was a pain in the butt to get it to work so this time I just want to buy one. The car is now running BBK headers into 3" pipes with flowmaster one chambers,(drag car set up, I'm taking a drag car and making a street car) I want to drop down to a 2.5" pipe, x pipe, and magnaflow or slp mufflers and LX tips out the back. Thanks guys!
