What Makes The Mufflerman One of the Best Car Repair Shops in Woodstock? At the Mufflerman, we are steadfastly committed to our three core values: quality, service, and trust. That means delivering exceptional service at every visit, using only the highest-quality parts, and delivering clear written estimates and no-nonsense answers to your questions. We don't want there to be any confusion when the final bill comes; we're committed to transparency every step of the way. It's these values that have helped the Mufflerman flourish across southern Ontario since we opened the doors of our first location in Sarnia in 1964. Remember, Mufflerman locations aren't franchised; we're all part of the same company, meaning you'll get the same excellent service in London, Strathroy, or Chatham that you do in Woodstock. more...
