For owners of a 2010 Ford Mustang with the 4.0L engine, we offer this stainless steel cat-back dual exhaust system. The Force II system features all mandrel-bent 2.25-inch stainless steel tubing with our exclusive Scavenger X-pipe for maximum power and a deep unique tone. The system then flows into a pair of specially-built 60 Series performance mufflers for a mild interior tone. The system is finished off with a pair of highly polished 3.50-inch 304 stainless steel tips giving your V6 the look of a Mustang GT. Carefully engineered for a precise fit, this system provides the performance and efficiency gains you've come to expect from Flowmaster and is covered by our Limited Lifetime Warranty. Note: This kit requires modifications to the rear bumper valence to accommodate dual pipe exits.
