    Comments about Flowmaster Inc. 40 Series Muffler - 2.50 Offset In / 2.50 Center Out - Aggressive Sound:

    The old mufflers on my 68 Camaro blew the baffles loose in the existing thin walled mufflers. I love the sound and durability of the flowmasters. These mufflers fit the floor tunnel perfectly and are a compliment to the floor pan. I feel these are the best muffler on the market for any performance car or any v8 vehicle that is a recreational or occasional driver. Most of my friends have flowmasters on their vehicles. When I need mufflers for any of my other vehicles I will diffenitely consider a flowmaster if one is available for my application.
