I wouldn't count on two much of a power gain from a gutted cat. If anything just take it out and put in a straight pipe.

I wouldn't even bother doing any of that, the power increase will be so minimal you won't even knotice, its not worth polluting the environment so you can have an extra 1/2 horse power (if that), save up and go buy a high flow cat....

I agree, a properly working cat has minimal back pressure.
Give a hoot don't pollute. GL

yeah and you dont want to breath that shit in... it's bad for you...and it dosnt do shit for your car(maybe make the back really dirty)

yeah, no gains will be seen.
