[heavy-chevy]

exhaust is more important, especially if its an lly it has a cat, get rid of it. cooler egts, better millage, and a little better throttle response. intake is pretty good factory on the d max but youl see a little bit better throttle response with one, theres really no advantage with a full intake over a drop in and a swiss cheesed box though. and itl make it sound way better, turbo will really whine especially if its an lly, them vvt turbos sound nice.
