With gains I've seen on the dyno between returned and atmospheric dump EWG's I will never run an internal unless its for a street car. Even then, I personally won't.
Micah never going to run the ewg back to the exhaust.. was wondering if goin to 3.5" will be beneficial over the 3"..

Which to ur answer is a resounding yes..
