I talked to my local truck shop, Trick Trucks, and asked what their thoughts were on it and possibly a cold air intake to boost horsepower and torque, maybe improve fuel efficiency. They’re honest guys and said if you do ALL the improvements together you will get a few more HP but mainly you’ll get good sound. You won’t feel a seat of the pants gain. Their opinion it was an expensive proposition for not much return on investment. I’ve watched the YouTube videos and it certainly sounds good and does lighten the truck by about 30 lbs. Post a video if you get one, it would be cool to hear your opinion.
