      Description

      Aggressive Sound. Let them know you're coming with the Flowmaster 40 Series Offset/Offset Oval Muffler. With its generous 3-inch body diameter, this exhaust upgrade delivers a more aggressive (though still street-legal) exterior tone and a noticeable interior resonance that will have you feeling (and hearing) the true power of your 'Stang.

      Increases Torque/Horsepower. Is your stock muffler robbing your 'Stang's performance? The two-chamber, precision-deflector design of the Flowmaster 40 Series Muffler supercharges your exhaust, giving you a marked increase in torque and horsepower.

      Tough Construction. The Flowmaster 40 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. 40 Series Mufflers also don't have any packing, so there's nothing to blow out.

      Modifications Required. This Muffler was designed to be used on mutliple applications, as it is not a direct fit replacement part. In order to install this Muffler properly on your vehicle, some modifications to the exhaust system will be required.

      Application. The Flowmaster 40 Series Oval Muffler is built specifically to fit all 1979-2004 Mustangs, excluding 1999-2004 Cobras.
