The best sounding MK3 Ford Focus RS catback exhaust is here to give you an insane driving experience like no other. The Agency Power Signature Exhaust is 100 percent Made in the USA . The custom built system provides just the right sound and gains the best performance. After testing different types of mufflers and valve setups, Agency Power created this full 3 inch catback exhaust. Its rally inspired sound turns the standard 2.3L Ecoboost Focus RS into a fireball spitting, downshift popping, and decal gurgling machine as you tear through the RPMs. However when you are cruising to the store or work, the exhaust is tame and keeps power just at the touch of the throttle.
The system is designed to bolt up to the stock downpipe or other stock replacement downpipes. Utilizing precision cut flanges and TIG welding to the T304 stainless steel piping, each exhaust is handmade per order with meticulous detail. The exhaust fits flawlessly with its straight design through the center of the vehicle which then splits in a beautifully merged Y out the rear of the car. The exhaust features dual 4.5 inch, slash cut, chrome tips which provide a more aggressive look to the back end.
Because the Ford Focus RS requires the factory exhaust valve to retain the Driving Modes, Agency Power supplies the exhaust with their valve delete box. The exhaust valve delete box is designed to simulate the resistance and function of the valve. It is enclosed in an aluminum housing featuring CNC machined components which is then mounted under the chassis of the vehicle. Once installed, your 2.3L Ecoboost Focus RS transforms into an animal without effecting your drivability.
