Good quality. Did have to trim off 4" of intermediate pipe even though directions said not to on 2011. Flowmaster staff very helpful. Sounds deep with very little drone in cab. Picked up 1-2mpg.

Install was a little tricky, Had to cut the old pipe to get it out. Some of the hangers didnt line up, but once I put it on I love the way it sounds. Have had tons of compliments!
