A shop that I use often only charged me one hour laber to do the install. Worth every penny because they stand behind their work. The 50 Series has a really deep tone through out all the gears. I do have some drone sound during low speed cruising. I had Corsa on a previous GMC Sierra that the tone came alive when you stepped on the pedel, which was a nice aggressive sound. If you want to always hear a deep tone, the The American Thunder 50 Series HD Flowmaster Exhaust System is it.
