Unleash a raw and rowdy sound from your Focus RS with this 3-inch cat-back exhaust system. Reducing restriction for better performance and refining the sound with a high-flow muffler and resonator, this exhaust takes your Focus to the next level.
Rowdy sound. With the active valve closed, the exhaust is directed through the high-flow muffler for a sporty sound that suits the aggressive styling of the Focus RS. When the valve is opened, the exhaust bypasses the muffler for a raw, race-ready sound.
Increased performance. The improved exhaust flow from this kit nets you gains of up to 11 horsepower and 15lbs-ft of torque. When combined with additional upgrades, aFe has dyno-proven results showing greater gains from the improved exhaust flow.
