Focused Performance in a DIY Package
Our Ford Focus RS Cat Back Performance Exhaust and is handcrafted in T304 stainless steel. This system includes three-inch CNC mandrel-bent tubes and dual four-inch double wall-polished T304 stainless steel tips with beveled edges. This system is engineered for the best sound to match your vehicle and provides substantially increased horsepower from the increased exhaust flow. Installation in your driveway or backyard takes about an hour using tools you likely already have.
For customers with factory-installed active or dual mode exhaust valves, MRT offers and recommends a simple solution that allows you to upgrade your exhaust system without having to develop a tune. Our Ford Active & Dual Mode Exhaust Power Plate mimics the stock flapper valve so the check engine light (CEL) doesn't come on. Simply add it to your shopping cart before checkout - it only adds another 30-60 minutes to the installation time.
