I have HFC's and a cat back. That along with a Stillen Gen III air intake and my car came alive. It sounds good and runs better. Very noticeably faster.

It wasn't that much more in the grand total of the exhaust so I just did it. I do have the SES light on right now though. Waiting a while for break-in so the computer re-learns the O2 readings and I'll have it cleared.
