Bought this system for my 2011 silverado Sounds great, looks great. The only down fall was minor. One of the ehaust pipes coming out of the side of the truck was off by like 1/8 of an inch, had to heat with a torch and bend to make it perfect.

As advertised- 2010 Chevy

Worst part of installation is removal of stock exhaust. Installation was pretty easy. Nice clean look. Sound is just right.

exhaust fitment not correct for vehicle

When I placed my order, I provided detailed information about the vehicle to the sales rep, including engine info, bed length, cab size, etc. A professional auto tech installed the exhaust system, and it looks terrible. He explained to me that at the overall unit was several inches too long for a proper fit, causing binding and a crooked installation. He informed me that the pipe would have to be disconnected, measured, cut to fit, and then reinstalled. He was hopeful that this would creat a proper fit. I did not expect this extra labor. Disappointing at best. We'll see how it turns out.
