This was an easy install. The instructions will not cover every wire bundle clamp or clip, so be patient and exercise some common sense. I installed this on a 2017 Chevy 2500hd, 6.0. I have noticed about a 2 MPG improvement. It sounds good when you accelerate. As far as a power increase, I haven't measured it. However, the muffled roar it creates when you step on it, certainly provides an Impression of HP increase.
