Done by myself… was a little frustrating because all parts would not go together easily. But once past the muffler it was cake. Like others have posted the bolts on the chrome tips are crap. Broke them both and had to buy new from local hardware. Other than that sounds amazing!

Mufflers sounded great except I have 2012 Camaro convertible and was not told by salesman from auto accessories garage that these did not fit on a convertible after much modification my mechanic was able to somehow make them fit.

I was really impressed in how well the exhaust fit and how well it went together. It sounds great with the headers I have for the truck and I would definitely get another.

Nice system, sound is very nice without being overpowering! Easy install, only issue I had with it was the bolts for the chrome tips either were to soft or needed washers! I broke one of them before it snugged on tail pipe. I got the hardest SS bolts,nuts,& washers from the local ACE store & that worked out well! Would have been 5 star if not for that issue.
