Rich, Sporty Tone. With its unique three-chambered style, the Flowmaster 50 Series Delta Flow Offset/Offset Oval Muffler gives your Mustang that distinctive sporty exhaust tone you've come to expect from this legendary manufacturer. What's different this time around is their new Delta Flow Technology, a proprietary design that decreases your interior cabin noise, giving you a rich sound on the outside and a quiet space on the inside.

Increases Torque/Horsepower. Is your stock muffler robbing you of your 'Stang's true performance? The three-chamber design of the Flowmaster 50 Series Muffler supercharges your exhaust, giving you a marked increase in torque and horsepower.

Tough Construction. The Flowmaster 50 Series Offset/Offset Oval Muffler is crafted from durable 16-gauge aluminized steel and is completely MIG-welded for the ultimate in strength and durability. 50 Series Mufflers also don't have any packing, so there's nothing to blow out.

Cut & Clamp Installation. Flowmaster makes it easy to install the 50 Series Muffler. With the proper clamps and hangers (not included), installation should take you less than two hours.

Application. The Flowmaster 50 Series Oval Muffler is built specifically to fit all 1979-2004 Mustangs, excluding 1999-2004 Cobras.
