That's the one reason I like to do my own from scratch with the mandrel bends. I installed the Pypes X 2.5 system on my Firebird when my buddy owned the car. Spent an entire day cutting and fitting it, and it still rubbed the pass. tire. On his previous '69 Firebird, I scratch built the system, and it cleared everything, and was hidden way better. I have a box full of 3" aluminized bends waiting for the El Camino. Just have to pick up the straight pipe. Napa sells it locally.forcd ind said:i bought one for my 70, but to get it to my liking i had to do a lot of cut and welding, esp the tailpipes
