You don't wanna do that. It will sound like ass, more than likely throw a code. You best bet, would be to either, buy the pre-cat, buy one used on ebay or junk yard, or buy a header set-up. The header will eliminate the pre cat, but you will have to extend one of the o2 sensors. Otherwise your at the cel deal again.
It will really sound like ass if you gut that pre cat.
