Built specifically for the 2013-2018 Ford Focus ST, the MBRP S42013CF cat-back exhaust replaces the full factory system from the catalytic converter back with mandrel-bent T304 stainless steel tubing and a dual-outlet configuration that looks and sounds the part.
T304 stainless steel construction. The entire system uses T304 stainless throughout, resisting corrosion and heat cycling across years of daily driving and track use alike. Mandrel bending keeps tube diameter consistent through every curve, so exhaust gases move without restriction.
Three-inch diameter tubing. The 3-inch main tube flows more exhaust volume than the stock system, letting the 2.0L EcoBoost breathe freely at full boost. Less backpressure means the turbo spools faster and the engine moves exhaust out of the combustion chamber more efficiently.
Dual outlet with carbon fiber tips. The system exits through a dual-outlet rear section capped with carbon fiber tips, giving the Focus ST a visual upgrade that matches the factory Sport design language without looking out of place.
Cat-back fitment, no fabrication needed. The system connects at the catalytic converter outlet and uses factory mounting locations throughout. No cutting, welding, or custom hangers are required to complete the installation.
