Built to customize your Ford truck to your personality, this direct-fit muffler bolts into the factory exhaust system and delivers an aggressive-to-moderate tone without sacrificing everyday drivability. Whether you’re cruising, hauling, or towing, this Flowmaster muffler is a straightforward way to shop for exhaust that improves both sound and performance.
Key Benefits
At the heart of this cat back muffler system is a Flow FX series “straight-through” absorption muffler constructed entirely from durable 409 stainless steel. The 409 stainless body, piping, and tubing are designed for years of trouble-free service, standing up to heat and the elements far better than mild-steel alternatives. A 3.50-inch inlet feeds into the round, 10-inch-long muffler body (4.5 inches wide) and out through a matching 3.50-inch outlet, with center inlet and center outlet locations for a clean, factory-style fit.
This performance muffler system is dyno-proven, delivering max gains of 12 horsepower and 11 lb-ft of torque at the rear wheels. That translates into better acceleration and improved towing performance you can actually feel behind the wheel of your Super Duty.
