On road or off

[GraGhst]

I've been thinking bout pulling my cats off, but I want to know if that will really make that big of a difference in hp and tq. I know it will be loud as heck, and change the sound. Does anyone have dyno numbers on b4 and after cats. Do they really make that big of a difference. If so how much hp and tq am i looking at here.

You'll lose a little low-end tq but you'll gain probably 10 horses up top. This is with an o/r x-pipe at least.

If you really want a catless exhaust, get an offroad pipe, and keep your factory one incase you need it for inspections. From reading posts, an offroad h will be 4 times as loud as stock. I would suggest a prochamber, personally, atleast that is what I am going to run.
