Built specifically for the 2016-2018 Ford Focus RS, the MBRP S4203AL cat-back exhaust replaces the factory system with a 3-inch aluminized steel setup that flows more freely and delivers an exhaust note worthy of the RS nameplate.
Three-inch diameter tubing, start to finish. Larger-diameter piping reduces exhaust backpressure across the RPM range, letting the Focus RS 2.3L EcoBoost breathe out as efficiently as it breathes in. The result is a more linear power delivery and a stronger pull through the mid-range.
Dual outlet configuration. The cat-back exits through a dual-outlet rear setup that fills the rear valance cleanly and gives the RS the aggressive stance its appearance demands. Tips are finished to complement the factory rear bumper cutouts.
Aluminized steel construction. Aluminized steel provides solid corrosion resistance for daily-driven and spirited street use, keeping weight and cost in check without sacrificing durability in normal operating conditions.
Straightforward bolt-on installation. The system connects at the factory catalytic converter outlet and uses OEM mounting locations throughout, so no cutting, welding, or fabrication is needed. A standard set of hand tools and a jack stand is all the hardware required.
