ok i just recently installed a shorty header on my 2003 zts and when i start it up it starts to sputter until it eventually shuts off. Is this because i have an air leak or am i supposed to get an 02 cheater as well or could it be both. i cant really check for air leaks cause im the only that lives here so i was wandering if thats all it would be.

stock cat? if so i would say that is probably your problem. the cat is probably clogged. but that is just a guess. you could try and pull the cat out and stick something down in it like a pry bar and knock as much stuff out of if as you can. however this might lessen the effectivness of the cat which could hurt your emissions if thats something you are worried about.

oh and you dont need an o2 cheater for a shorty header, only race headers or ofp's

would gutting fix the problem?

if ithe cat IS your problem then, yes!, but if it's not... well you'll have a gutted cat. Did you have trouble with your car before the headers??

no

hhhhmmmm... can't really point out what could be going wrong.

would and exhaust leak cause it to sputter and cut off?

i guess not... have you checked for a vacum hose, maybe something got disconnected.
