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.
Good but outlets are not even....

great sounds exhaust, it is louder than you might expect but has an amazing sound overall! The tips and system are well made and high quality. However the outlet pipes are not even, support bar that is welded between them may be too week. Would like a replacement if necessary.
