From Exhaust Shop To Full-Service Auto Repair… Get To Know Muffler Man Mechanical

Dwayne and Shawna Bullock opened Muffler Man in Grande Prairie in August 2005, focusing on custom exhaust work. In April 2016, they took over the auto repair shop next door, Perfection Automotive, and changed the name to Muffler Man Mechanical in August 2017 to reflect the business’s change of ownership and Muffler Man’s expansion into full-service auto repair. The Bullock's strive to provide honest, quality auto repairs for Grande Prairie and area.
