Built specifically for the 2013-2018 Focus ST, this MBRP cat-back exhaust replaces the factory system with a 3-inch T409 stainless steel pipe and a dual center outlet configuration that opens up exhaust flow and changes the character of the 2.0L EcoBoost completely.
T409 stainless construction throughout. T409 stainless steel resists corrosion and heat cycling across all four seasons, maintaining structural integrity whether the Focus ST is a daily driver or a weekend track car.
3-inch main pipe diameter. The larger bore reduces backpressure compared to the factory routing, letting the turbocharged 2.0L EcoBoost breathe more freely and deliver a more linear power curve under boost.
Dual center outlet with black tips. The dual center outlet exit positions the tips at the center of the rear valance for a purposeful, symmetrical look. Black-finished tips add a distinct, aggressive contrast to the rear of the car without requiring any additional trim work.
Direct bolt-on fitment. MBRP engineers the S4200409BT to use factory mounting locations and hangers, so installation requires no cutting, welding, or fabrication. The system goes on with basic hand tools and a lift or jack stands.
