"I recently had Griffin Muffler and Brake Center put a complete new exhaust system on my 2005 Dodge Ram and all I can say is WOW! Griffin's staff are second to nobody. The installation was Outstanding, the mechanics are great and was charged a reasonable and fair price. If you are in SE Iowa and are in need of Professional Car Service I would highly suggest Griffin Muffler where they do make you feel like you are their most important customer. "
