"The Flowmaster 50 muffler is awesome. It has a great outside sound while still being quiet inside. I installed it on my 01 Yukon. The price is awesome for what you get. And you know the quality will be there with a Flowmaster. It sounds powerful without taking away the luxury look and sound of my SUV." posted by: on March 11, 2011 view all 2 reviews
