Grande Prairie’s Friendly, Neighborhood Muffler Man & Full-Service Mechanic


Muffler Man Mechanical is a family-owned, full-service auto repair shop in Grande Prairie, AB. Our name gives it away—we started out as an exhaust and muffler shop, and we continue to offer custom exhaust and muffler mods—but we saw a need in the Grande Prairie community for honest, quality auto repairs, and we knew we could meet that need. So, here we are offering total auto service and loving it! We get to know our customers and their vehicles inside and out, and we can make a real difference in people’s lives simply by doing what we do best—fixing cars and helping others.

Dwayne and Shawna Bullock -  Owners of Muffler Man auto repair shop

An Auto Repair Shop Love Story for the Ages


As kids, owners Shawna and Dwayne Bullock spent their summers travelling with their parents to hot rod events around Saskatchewan. The kids at these events would all hang out together, and that is how this couple met. Dwayne worked at his dad's exhaust shop, and would have kept working there, except he had met Shawna, and she lived 5 hours away.

So, at 16 he moved to her town, got a job at the local exhaust shop, and the rest - as they say - is history.

Get Bent! (In the Best Way)


At Muffler Man Mechanical, we’re building on the excellent reputation of our exhaust shop to offer customers, both old and new, a complete—and completely awesome—auto repair experience. We stress honesty, integrity, quality, and attention to detail at our shop, which extends to making car care as comfortable and convenient as possible for you. If you need to leave your car after hours, we have a secure 24-hour key drop, and if you're passing the time with us, enjoy coffee, refreshments, and free Wi-Fi.

Proudly Serving Greater Grande Prairie


Our auto repair shop is located at 9455 116 Street in Grande Prairie, AB, south of Costco and convenient to both residential and commercial areas. We also serve the communities of Fairview Valleyview, Grande Cache, Beaverlodge, and Spirit River.

We’re proud to be part of such a diverse community, where small, family-owned businesses like ours successfully rub shoulders with large companies. Our customers are just as diverse, ranging from Grande Prairie residents with deep roots to oilfield workers and their families who just moved to town. Our goal is to earn the loyalty of every driver who comes to our shop by consistently providing honest, accurate, and reasonably priced auto service.

Giving Back Drives Us Forward

At Muffler Man Mechanical, our service to the community goes beyond car repair. In Fall 2017, we held a Red Cross fundraiser for Wildfire Relief, and Dwayne is an active member of the local UCT/ACT, raising funds for people with mobility challenges.
