Tough installation, but great performance
I don't usually have much luck as a do-it-yourself product purchaser so I had my trusted auto repair shop install it (good thing). They had to order a special clamp because the one provided didn't fit properly. They also had to bead weld the exhaust pipe to the last hanger at the rear of the Tahoe to keep the exhaust pipe from touching the rear quarter panel where the pipe extends below the body. Other than the installation issues, it increased hp & mileage & sounds great!
