anyone have any laying around they want to part with??? I think I need them...........Off Road X with Headers and Loudmouths is a bit much for me

will your stock h-pipe with cats mount back up to your shorties? if so, then that would be the way to go.The cats that came on our cars stock were already high flow...i think the only real performace gain comes from eliminating the cats all together.

Yeah it would definately mount up, I just like the X better than the H and I spent the 200 bucks on it already..........Maybe I'll try hanging the stock mufflers back on it and see how that goes for a while..............The more I think about it I should not have gotten the X in the first place, but it's too late now

in terms of performance, there's not a big difference in power between stock cats and high-flow cats.

in terms of sound, there's a huge difference. the Bassani race cats are much much louder than the stockers

Brenspeed reports that the Kooks setup with no cats is only good for another 2-3 hp when compared to adding the cats back in.
