Mellow, Mild Sound. Enjoy the legendary performance of Flowmaster without a deafening exhaust note. The Big Block II 70 Series muffler improves your exhaust flow, releasing hidden HP and TQ and giving you more ponies to help you haul even the heaviest loads up steep grades. This muffler is perfect for any vehicle frequently used for towing - giving you better fuel economy and power without increasing the volume of your exhaust note.

High Flow. In order to get more power without more volume, Flowmaster used their patented Delta Flow technology and enlarged the 16-gauge aluminized steel case. And to ensure this muffler's long term durability, it is constructed with all MIG welds. And with the case stamped with the Flowmaster logo, this muffler looks as good as it performs.

Fits Most F-150s*. The outer case of the Flowmaster SUV 50 Series muffler is 25" x 11" x 6", allowing it to be used on most Ford F150s with a dual exhaust. It features an offset 2.5" diameter inlet and outlet, and is priced and sold individually.
