Immediate Performance Gains. The Flowmaster Super 50 Series Offset/Offset Oval Muffler (2.5”) is designed to provide a performance boost for large displacement engines, just like the one under your Mustang’s hood. By allowing for a more effective exhaust flow, the offset/offset muffler will boost horsepower, torque, and overall engine efficiency. The Super 50 Series mufflers improve upon Flowmaster’s well-known 50 Series mufflers, offering new innovations in design, materials, and construction.

Tune Your Mustang’s Roar. The goal of every muscle car owner is to achieve that natural, rich race car growl without reaching obnoxious volume levels or adding a low-quality whine. Designed with a tuning chamber to reduce interior resonance and a larger case to allow for better sound control, the Super 50 Series muffler achieves this goal perfectly. You will keep the mild to stock exterior exhaust tone and minimal interior resonance, while refining the classic tone of your Mustang’s natural sound.

High-Quality Fabrication. Flowmaster products are American-made, so you can be confident that they have held every single muffler to the highest standards of quality and construction. Made from 16-gauge 4095 stainless steel and fully-MIG-welded, the offset/offset muffler achieves the ultimate in durability. You won’t have to worry about losing driving time to make repairs, because the Super 50 Series muffler is made to last.

Limited Lifetime Warranty. Flowmaster backs their mufflers with a limited lifetime warranty.

Application. The Flowmaster Super 50 Series Offset/Offset Oval Muffler (2.5”) is designed to fit 1979-2004 Ford Mustangs, with the exception of the 1999-2004 Cobra models.
