Customer photo review of GM Duramax LML Down-pipe Back Race Exhaust (2015.5-2016)

Arrived on time. Went together better than expected. Starting the slip connection was challenging, but once I got it to line up, went together well. I adjusted one of the mounting rods (bent it) so pipe and muffler wouldn’t hang below the frame. Installed the 5” pipe and muffler, fitment is excellent, no contact with anything that will create a rattle, including air bags. The connection flange fit perfectly (late model 3 bolt style) I’ve installed several mail order exhaust systems, this one was the easiest. I have the advantage of a lift, took about 4 hours to install. You could easily install this with your truck on jackstands. Noticeable power increase with the skinny pedal. Looking forward to the mpg numbers. Just slightly louder than the stock pipe, but that was my goal, a sleeper truck.
