I received my exhaust system on time in good shape. I'm a bit too old for rolling around my driveway in the winter months so I had my trusted mechanic install it. I took them about an hour with a couple of interruptions, but he said it was "easy-peasy" and straightforward. It is a little louder than I expected (my girlfriend says) but is music to MY ears. Very throaty and sweet sounding. Great price and a really nice looking system.

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.

I had a local muffler shop complete the install of my Flowmaster super 44. Great fit and super sound. My truck is looking sharp and sounding even better. Thank you and will be back for my other truck.
