Easy install. Made a noticeable difference immediately. I can hear my 5.3 starting to come alive! Next is exhaust.

I wanted my truck to have a little more oomph and I got it big time! The sound is awesome when you get on it and not obnoxious at all. My mpg would be better if I could only keep my foot off the petal. If you want a nice sound that isn't over powering this is a must buy
