I really want to order this stuff, but first, how does it sound? Are the IROC-size headers better or does it lose too much torque? Does the cat fit or will I need some installation kit or welding? How do you like it? Thanks a lot, fellas.

If u get the TES Headers #6872 (IROC-Z ones) then u will need to make sure that the catco cat is a 3" inlet because thats what the Y-Pipe open up at. I am unsure on what the Edelbrock Cat-back opens up at on the outlet side of the cat but u will need to make sure that the cat is equal with that too.
