I want to put a cat back exhuast system into my '95 riv but i cant find any kits around for the life of me. I'm going to be putting on dual super40 flowmasters, but my friend says that to add any real noticable difference in performance i will have to go cat-back. Any thoughts on whether or not it is worth it to try to go cat back vs. just getting the new mufflers? Also, more importantly, anyone know WHERE i can find a kit??? I've been looking for a few days now all over the net...no luck!
