Unless you are running a tune. It wouldn't be my first mod though...I would do a tune, exhaust, charge pipe, DP's, etc.I like my afe. .but it's all about sound. Neither will change performance.

Good move, unless you're going with catless downpipes as well, you won't see any big improvement with a catback. The tune is the number one choice.I'm doing a southern speed tune. Leaving the exhaust stock for now so basically just doing a intake charge pipe and tune
