Hey guys,
Does anyone know the diameter of the stock H-pipe on a '95 GT?

 

stock exhaust is 2.25".

 

bingo. IIRC that's the stock size for any 79-04 v8 powered GT.

 

Really? I had someone on another forum tell me that it was 2.5". How come the inlet pipe on just about every GT catback for a '95 is 2.5"? I want to put a flowmaster setup on my car but all the full setups that I have found have 2.5" inch pipes. Will that work on my car?

 

All aftermarket catbacks are either 2.5" the norm or 3" thats because there bigger then stock to flow more air. stock piping is 2.25" or 2 1/4" whatever you like to see

 

Ok so will the catback work with my stock exhaust h-pipe?

 

yes it will bolt on.

 

Cool thanks.
