These guys know what their doing! 2-1/2" and it all fit perfectly, I did have to shorten the long tubes out of the headers to the H-pipe (per instructions) then had to shorten the over-the-axel to tail pipe tubes for personal preference on exhaust tip exit, but all bends and both mufflers located perfect. Even came with factory style high quality hangers to mount in factory holes! WOW! Strong big clamps and even high quality grade 5 bolts. They supplied 3/8 flat washers for the 5/16 bolts, but I supplied my own to correct that. After a couple of hours I was extremely impressed!!! Probably at least a 2-man job, but I'm a one man crew. 8) ...read more

thrush exhaust system 89023

This exhaust did NOT fit my car at all - 1965 Chevelle 327 V8. I gave up on it and took it to a pro. shop to have them install it. The interim pipes - X pipe did not work at all with the factory trans mount - cross member. (didn't match up to the "humps" for clearance). Only parts of the system that somewhat worked were the tail pipes and the mufflers. The rest was a waste.. ...read more

Great upgrade over the previous owners attempt!!!

Summit RacingSummit Racing Verified Purchase

I bought this system to replace a pieced together mess installed by the previous owner of our 1969 Chevelle. This system fits very well, my only complaint about the fit is that the turndowns stick out 4" past the bumper. That was easily fixed by cutting the turndowns off and fitting some polished stainless tips in place. I took the time to weld all of the connections instead of using the included clamps, and was able to complete the installation about 5 hours. I also upgraded the mufflers with Summit chambered mufflers for a more aggressive sound. Overall I am very happy with the system. ...read more
