C3 Exhaust Pipe 334936 vs 3952732

[Sheldon S.]

The 334936 exhaust pipe is listed for big block 68, 70, 71,72,73, 74 RH Front pipe with turbomatic 400. 33952732 is listed for 1969 big block RH front pipe with Auto Trans. What is the difference in the cars for a different pipe. Will the 69 fit the others or is there a noticable difference. I have the other three pipes for my car but have not been able to locate this one. I have a 71BB. Gardner Exhaust in calif. is now producing BB exhaust systems but they do not have this pipe yet. Any help here would be greatly appreciated.
thanks

All 1969 Corvettes used 2" exhaust----from base engine thru L-88. So, the big block forward pipes were 2-1/2" at the manifold and necked down to 2". The 334936 is a 2-1/2" pipe. All other Corvette big blocks except 1969 used 2-1/2" pipes from the manifold all the way to the muffler.

By the way, I should have mentioned that GM #334936 is not the right front pipe originally used for your 1971 LS-5 with THM-400 application. The pipe originally used was GM #3921600. The 334936 was the 1973 PRODUCTION and SERVICE pipe which became SERVICE for earlier models.
