The muffler arrived with one side scraped up which wasn't a concern for me. Installation was easy. Just make sure you have clearance where the tail pipe bends next to where the spare tire heat shield is located. I had to cut and reposition the rear hangar to move the pipe over about an inch. The 50 series is quiet and slightly louder then the stock muffler. I was told by the sales person that the 40 series was ubnoctously loud and I should get the 50 series. I should have gone with the 40.
