got a 2 1/2 in h-pipe from summit. just wondering as to what size my header collector had to be

[FOX347]

I have the same pipe and I have a 3 inch collector and used a reducer to make it compatible with the rest of the exhaust. If your not sure on your collector size, give summit a call and explain what you have and they are most often able to give you some good advice as well as part numbers that you will need.

thanks. but what do you mean by a reducer

[FastStang91Lx]

A piece that goes from 3 inch down to 2 1/2

If you do call summit, take what you hear with a grain of salt. I wanted a cheap h-pipe for my longtube headers that had a 3" collector with flange ends on them and the guy recommended a BBK pipe that was a 2 1/2" with a ball and socket end on it. If I would have ordered it without looking first it would have been the wrong part. I even gave him the part number to the headers that I bought from them and he still said that part would fit. Just looking at it it wasn't even close and the guy tried to push it on me. I ended up having to take a shot in the dark at which one would fit and got a hooker mid pipe that worked.
