This is a true interference fit exhaust system

I first put this on my 71 and had a muffler failure. That system did not fit well and interfered with the drive shaft and pinion snubber bracket. The manufacture replaced the full rear segment system under warranty. Kuddos for them on that. How ever the replacement system had a bunch of things not the same as the first. 1, both tail pipes had a turn inboard near the end, first system only the L/H one did. 2, both intermediate pipes were different then the first ones. New system interferes with the drive shaft, Pinion snubber and 1 lief spring at the rear. Recommend if you do buy this have a competent shop install it as they will have the tools to make needed adjustments to the pipes.
