72 exhust tips
Just droped my rebuilt 350 back in my car and would like to go to 2 1/2 " exhaust. My question is did the LT1 and the 454 vettes have 2 1/2" exhaust tips or 2" as I don't see different tips in the supply catalogs that I have for the 72's.

2 inch tips. The mufflers had 2 1/2 inlet and 2 inch outlets.
I did put on a set of 2 1/2 Flowmasters and they had a 2 1/2 outlet. I took out the 2 inch pipe in the tips and hogged out the hole and welded in a 2 1/2 pipe. Looks stock and you can't tell anything was done.

That far down the exhaust there is really no performance to be gained. The exhaust has cooled a lot by then so you don't need as big a pipe. I did it because the mufflers were 2 1/2 and it was something different. Unless you have a real heavy breathing SB or BB, 550 or greater HP you do not need to do this.
