Honestly IMO you are going to gain WAY more by putting a EL header and aftermarket overpipe on the car than switching your catback.
So the tomei EL is what you'd recommend? what about the overpipe / front pipe? While I'm at it should I just do the front pipe as well?

My goal is the EL / OP / FP / E85 tune hoping to keep my catback so I don't have to spend that extra money for a catback.
