    I wouldn't do it. Your car was meant to run with a cat and its not a turbo car so that back pressure is good for your low end power. Unless your car is turboed. In that case hollow away.

    It will add power, but like everyone else has mentioned already, your car will be louder and will smell like an old truck driving down the road. And if you get caught, its a hefty ticket. You'd be better off purchasing a high flow cat. They can be had at most local muffler shops for around $90. Of course, that depends on the shop. I always get mine in 3" in/out and have them neck it down to fit my exhaust.
