my girlfriend has a 94 mustang 3.8. She has a hole in her exhaust and loves the sound of the dual exahust so I need some help on the cheapest way for a full exhuast. I talked to some guy at 50resto and he told me if you want a "true" dual exhuast you need to go from the headers back. What company offers a complete kit for this and how much is it going to cost. What do you suggest doing with the back bumper to get it so the dual exhaust will fit out of the back? Help Please!
