Is this piece worth porting? Is there a way to port it? I've heard that the main power robber is the stock cat on our cars. I have a Borla already and I don't want a header as my car is loud enough as it is. Could I just port the manifold and replace the cat with a high flow one and some bigger tubing?

no, not at all. u couldnt reach enuff of what u needed. plus exh stuff has 2 b mirror finish unlike intake where it can b etched or rough. besides the stock cat doesnt like any extra flow, run the risk of killin it.

just hang tight w/it...then move on when money allows.

a high flow cat will increase your exhaust sound a bit..
