f you're not concerned about emissions testing you can gut the catalytic converters with a prybar or other long sharp instrument. That's worth i'm guessing 5-10 horsepower and that's also free. If you gut the cats you can run a short belt to bypass the smog pump and that will give you up to another 5 horsepower i believe.

Don't do it!!!!!!! its not worth it. if u want to run no cats just buy and off-road h-pipe, and switch back to the stock pipe for inspection. i'v heard gutting the cats is bad and doesn't do much besides lose power. as for the smog pump it doesn't really take any power to run, there for useless to bypass, unless you are running a drag car or something.
