Guys,

I am attempting to harness a few more ponies out of automatic GXE I have, and was considering either installing a catback system or just change the muffler.

I will more than likely install a filter charger upfront, or at the least, a K&N filter.

I am stuck on the decision regarding the catback vs muffler since I do a lot of highway driving along the east coast and am leary of the drone emitted from most aftermarket syatems.

Is there a particular system I could install that would alow me to harness the ponies, increase performance, while not getting into the loud drone (mind well it is an auto tranny which won't sound too great droning anyway).
