Mac Cat Backs

Mac Performance is dedicated to building products that meet strict quality standards. We follow exacting guidelines during manufacturing in order to insure that you receive a quality, reliable product every time. We maintain a strong committment to customer service. We promise to do everything in our power to insure that your experience with Mac Performance meets or exceeds your expectations.

The first automotive production piece we made was the equal length header for the 5.0 Mustang. It was an industry first and is still frequently copied today because of its superior design and function. Next was the off road h-pipe for the 5.0 Mustang, the long tube header, and many other parts mostly for Ford vehicles. Eventually the product line expanded to Chevrolet, Dodge and Import cars. MAC Products now produces over 1200 parts for cars and motorcycles and the list is still growing.

True Fit design (ball and socket fitting) eliminates the need for gaskets, muffler clamps and welding. The system is made from 16ga aluminized tubing. All tips are chrome plated.

All MAC 3" systems fit to stock catalytic or any MAC off-road H-pipe or Pro Chamber.
