did it spent the money and installed it on thurday and i love it by far the sound i was looking for but im running the 2" pipe and was wondering if anyone started off with 2 and upgraded with 2 1/4 from the cat back does it make a bigger difference just looking for a lil more volume

Yes, 2-1/4 would give it a lil bit more volume, but I wouldn't go much bigger than that.
