We're a local San Diego automotive accessories retailer and we were searching for a mechanic or a shop to install some exhaust systems for an up-coming photo shoot. After dealing with a weasel of a mobile mechanic, we called American Muffler. Andy and his crew took care of us. We were warmly greeted, quoted a great price and received excellent, timely work. We look forward to working with Andy and the entire American Muffler team in the future! Thanks!
