    Menacing Rumble. Let your beast roar (within the legal limits, of course) with the Flowmaster 40 Series Delta Flow Center/Offset Oval Muffler. Its dual-chambered design and carefully-placed deflectors create more scavenging, which gives you a more natural exterior tone and keeps your cabin quiet.

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

    Tough Construction. The Flowmaster 40 Series Delta Flow Center/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 Delta Flow Center/Offset Oval Muffler is built specifically to fit all 1979-2004 Mustangs, excluding 1999-2004 Cobras.

      Flowmaster Delta 40

      Sounds great! Looks awesome! I ordered two of these for my 2016 White Mustang and I am thrilled! They look great with black exhausts tips; cost me less than a hundred fifty to have installed, and not a bad price for a top name brand!
