off road x-pipe or X-pipe w/cats, does it matter? what's the differnces bettween the two? which one makes more hp and torq? also what does catted X pipe means? is it the same as w/cats?
Here's a little more advise for you. An offroad (no cats) x pipe will sound alot nicer and give you a snappier throttle but a hi flow x pipe will give you more low end torque. I truthfully like the off road x pipe alot better but I went with a hi flow so I would be legal and dont have to worry about the sniffer!
