About Us

No hustle or hassle, no gimmicks or tricks – just fast, honest service!The Christensen family founded Muffler Man Auto Service Center in 1967. The first store location was and still is on North Saginaw Street in Flint. The organization has grown to 125 locations, with three main distribution centers in Michigan, Ohio and Florida. Rainbow Muffler is our name in the states of Ohio, Indiana, Georgia and Florida.

We are one of the largest privately owned, non-franchised dealership groups in the country. We offer a complete line of quality auto parts and services. The goal from the start was to offer a one-stop shop for auto and light truck repairs at the most affordable prices. Keeping overhead low and having large group buying power has helped us do just that. We will beat anyone’s prices, “apples for apples.” Most locations offer up to forty services.

Call the location nearest you or just stop in to meet the staff and get a free estimate. No hustle or hassle, no gimmicks or tricks – just fast, honest service!
