Cat-Back System Overview

Scorpion engineers have developed a high-flow 76mm (3”) cat-back exhaust system specifically for the Ford Focus RS (Mk3). This freer-flowing design improves exhaust gas evacuation, sharpening throttle response, enhancing power delivery, and reducing overall system weight compared to the factory exhaust.

The system retains full electronic valve functionality, allowing drivers to control exhaust volume and character using the factory drive mode selector. This provides the flexibility to enjoy a refined tone during daily driving and an aggressive exhaust note when performance is demanded.

Tailpipe Options

A range of premium tailpipe finishes is available to suit your preferred aesthetic:

• Twin 114mm Daytona – polished or black ceramic
• Indy style – polished or black ceramic
• Carbon Ascari – high-strength carbon weave for a distinctive motorsport look

Black ceramic tips undergo a meticulous coating process for long-term durability, while polished stainless steel tips are hand-finished to a mirror-like shine. Carbon Ascari trims are available as part of the system or as a standalone upgrade.

The Scorpion Advantage

Precision-engineered using CNC mandrel-bent tubing, Scorpion exhaust systems maximise exhaust flow and minimise restriction. Constructed from premium T304 stainless steel, they are built to withstand extreme conditions while delivering weight savings and improved performance over OEM systems.

Upgrade with Scorpion for enhanced acoustics, improved responsiveness, and a driving experience that truly elevates the Ford Focus RS (Mk3).
