Deeper, Throatier Exhaust Note without the Cabin Drone

Adding a more aggressive and throaty sound to your 2016-2017 Focus RS' 2.3L EcoBoost can be a pain, thanks to Ford's electronic balancing valve getting in the way. Luckily, our friends over at MBRP are here to help with their XP-Series 3" cat-back exhaust kit. The XP-Series Focus RS cat-back exhaust system features larger tubing than stock, a more aggressive muffler design, and features an included valve simulator to avoid issues with Ford's electronic exhaust valve assembly. The MBRP Focus RS cat-back exhaust kit replaces everything from your hot-hatch's downpipe back to its tips, giving your aggressive RS a full exhaust overhaul for a great sound and look.

3" Diameter, 409 Stainless Steel Tubing with New Muffler and Valve Simulator

The system is made using 3" diameter tubing that's all carefully mandrel-bent to ensure an excellent fit and minimal flow restrictions. The kit features an entirely new muffler than provides a more aggressive tone while on the throttle all without increasing cabin drone when cruising. Each kit comes standard with a electronic valve simulator that allows the electronic valve to prevent issues with your RS's electronics. The XP-Series Cat-Back Kit is made out of 409 stainless steel that can resist corrosion in most climates. The system is topped off with 4" diameter exhaust tips with a polished finish for a great look. MBRP includes instructions and hardware for installation.
