I had a defective catalytic converter on my SS/SC and the check engine light kept coming on. Do you get the check engine light?

BLOWIN PLUGS OUT OF THE HEAD?!?!?!?!?! WTF!

You mean it is blowing your spark plugs out? I think that's a whole nother problem brother. I drove on a bad cat for a while. Never heard of a plug blowin out of the head. But, you never know, crazy **** happens everyday.

you heli-coiled your head? did you back tap it, or use a regular tap? rip your dp off and gut the cat for now. thats bad news!!

those heli-coils are probably gonna keep blowin out. i've had bad experiences with them.
