    Smooth, Mellow Exhaust Sound. If you want your Mustang to sound more like Barry White than Black Sabbath, the Flowmaster 70 Series Center/Offset Oval Muffler is a perfect upgrade choice. Its large chamber and strategically placed deflectors give your Pony a mild, smooth tone while keeping your cabin resonance to an absolute minimum.

    Increases Torque/Horsepower. Is your stock muffler robbing you of your 'Stang's true performance? With its massive chamber, the Flowmaster 70 Series Big Block Muffler can accommodate maximum exhaust flow, giving you a marked increase in torque, engine efficiency and horsepower.

    Tough Construction. The Flowmaster 70 Series Center/Offset Oval Muffler is crafted from durable, corrosion-resistant 16-gauge 409s stainless steel and is completely MIG-welded for increased strength and durability. The 70 Series from Flowmaster is designed to be ideal for Mustangs with heavier payloads or towing.

    Cut and Clamp Installation. Flowmaster makes it easy to install the 70 Series Muffler. With the proper clamps and hangers (not included), installation should take you less than two hours.

    Application. The Flowmaster 70 Series Oval Muffler is built specifically to fit all 1979-2004 Mustangs, excluding the 1999-2004 Cobra.
