Easy install. Gave my Sierra a nice throaty grawl to it while punching it. Helped with HP as well.

Took maybe 20 minutes to install, went on no problem. I could tell a lil difference on the low end of the throttle and I could tell that it helped the truck breath and pick up better. Overall great product from air raid.

This thing is great. Can't comment on mileage yet, although the computer is saying I am getting lower than I have in a long time unfortunately. As for performance though, you can feel the extra horses kick in, not to mention the engine roars when you step on the gas. Sounds amazing with my flow master 40 muffler and dual exhaust. Highly recommend. The pictures are garbage on the instructions so just find the youtube video, or look at the schematic.
