Hi Im new to 6GC I bought a 94 st a week ago and Im fixed up some problems on it and I just wanted to know what the outlet size of my mufler pipe is. The muffler I bought is a has a 2.5" inlet and my cars didnt fit, mines too small so I want to get a little pipe having one side 2.5" for the muffler and the other side the size of my pipe. If anyone knows thnaks/..

bring it to a muffler shop, ask them to put it on there.

The outlet should be 1 7/8 inch. Any decent muffler shop can weld it up. I had one do that for me.
