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
