TNT sells high-flow cats for $495. Sorry, but don't know if they provide any real HP gain. Would like to know what other have to say though!!

Check with a company called Random technologies. They might make them for Vipers. I have heard that there is not much gain by doing this. Save your money and spend it on something else.

Good luck.

I've got the High Flow TNT cats, and I love them.. They sound great and the HP difference from straight 3" pipes (no cats, no mufflers) is only 3 HP. That says (well, on my highly modified engine) they flow every well. I can't tell you the gain from the highly restrictive cats are. I'm guessing that would depend on the mod.s to your engine and exhaust.
