Take your 2013+ Ford Focus ST to the next level with the Agency Power Exhaust Stainless Steel Catback Exhaust System. This system features a high-flowing 3" mandrel bent piping with a large resonator/muffler in the mid-section to improve exhaust sound and performance! The entire system has been polished to a stunning mirror finish and is available with the option of 4 different tip styles to choose from that are easily changeable with the V-Band Clamp Design.
As tested on a Mustang Dyno, the exhaust picked up a noticeable gain of power throughout the rpm curve. Peak horsepower and torque of approximately 10 was achieved between 4900 and 5500 rpms. Where this exhaust really shined was with the addition of custom ECU tuning and our downpipe to deliver huge gains of around 40 ft/lbs of torque and 40 wheel horsepower.
