Luckily, our friends over at MBRP are here to help with their Installer Series 3" cat-back exhaust kit. The Installer 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.

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 Installer Series Cat-Back Kit is made out of aluminized steel to keep the price of the system low. The system is topped off with 4" diameter exhaust tips with a polished finish for a great look.
