right now ive got edelbrock headers with single car y pipe, and a flowmaster exhaust, that is rusted to hell,

i dont really want to change the headers, to much of a pita, would i get any power gains from a dual cat setup? could i just buy a dual cat y pipe? what do you suggest for and exhaust? anyone try fitting the slp loudmouth on a 3rd gen?

 

I assume you mean just a Flowmaster muffler?

I'd look into getting a Hooker cat-back.

 

factory dual cat exhaust increased hp...
