Very good kit.

By Ryan B on January 3, 2020

This exhaust kit is very well built and looks awesome. Was a little quieter than I expected but still sounds great. Has a nice rumble on initial startup. It is almost silent cruising down the highway but once you get on the gas it sounds amazing. All of the pieces slide into one another easily and the clamps seal very well. I have not had any leaks in the kit at all. One thing I just mention though is that the supplied rubber hanger does not quite match the OEM hangers so I had trouble getting the tips to match under the bumper.
