I don't know what this would do so i figured i'd ask if anyone has done this. I guess my pre cats are going out b/c i got a code that my cat is going bad and that would be the only ones that it could be b/c of where the o2 sensors are placed. how would a svt run with no cat on it and can someone tell me how to gut the pre cats.

Amazingly enough, the post right below this one asks the same question, and has all the information you need.
