In my jegs catalog i see a hooker catback, # 520-16823, for 86-92 "HO" camaros. My question is is this system a 3" or 2.5" system, or a 3" in, 2.5" out system?

 

I think thats the one I got, and its a full 3" system, but call the guys at Jegs to be sure.

I have that system - same part number. The i-pipe is 3 inches and the pipes coming out of the muffler are smaller than the i-pipe. I can't remember for sure if they are 2.5 out but that sounds right.
