What Makes The Mufflerman One of the Best Car Repair Shops in Sarnia? The Mufflerman has been operational in southern Ontario since we opened the doors of our first location, right here in Sarnia, in 1964. Since then, our business has grown to include 12 locations in ten cities throughout the region, all while maintaining a presence in our hometown. That kind of longevity doesn't happen by accident. Over the course of our decades in business, we've continued to be guided by our core principles of quality, service, and trust. That means using the highest quality auto parts in all repairs, delivering friendly and caring service to every customer that walks through our doors, and always preparing clear written estimates for every job. Questions about our quote? We'll happily provide straightforward, no-nonsense answers; we never want our customers to be surprised when the time comes to pay their final bill.
