I run the TTI 2" headers and the full 3" exh system out to the rear bumber. I went with the X-pipe and it fit great and was simple to install. Ron

I’m running 3” X-pipe TTI system with tips on my 72’ RR/GTX, exhaust system fits well but as mentioned does not use some of the hangers originally used. Besides the need to add a floor mounted muffler hanger brackets as needed, the tail pipes have hanger tabs using a factory style tail pipe hanger forward of where the factory tips/hangers would locate. TTI’s repo tips don’t have hanger tabs and are designed to clamp to their “cut off” turn down tail pipes. The tips exit in the same position as the originals and will require a cut out or modified rear valance to fit perfectly. Other repo tips matching whatever pipe size tail pipe should work as well, may have to choose which hanger configuration. I’m planning to add some resonators to mine after recently going back to manifolds and will be reworking my tips and hangers to accommodate them.
