I was wondering if I punched out the stock h pipes cats wouldn't that be the same as getting an off road h-pipe? I mean Probably would gain 1hp out of it but the sound would be the same no??? debating on whether I should go this route or just pay the 160 for the x-pipe, thanks!

most aftermarket have bigger piping and are mandrel bent. flows a little bit better than a stock pipe with gutted cats

+1, but i think you should see more than 1 hp from it though!

I dunno just a rough figure! I guess I'll get the x-pipe and sell my cats to the junkyard
