Sounds freaking great! Clamps are kinda cheesy. Great buy!
Great bang for the buck

A straight forward, easy to install piece for the money. Fit was good, install took roughly 2 hrs on a lift with help working at a comfortable pace. Recommend an extra set of hands for the install, makes for reduced cussing. Clamps supplied were okay, nothing to brag about but expected for the money. Downpipe install was a breeze, easier to install than removing stock. Cutting stock downpipe halfway saves alot of headache. The finish product sound is excellent, not obnoxious, louder than stock, still quiet in cab cruising. Give it a few miles and the sound will change for the better as the muffler fills with soot. Overall very happy.
easy install
