Aug 18th 2025
Why Scorpion Stands Out
Motorsport DNA
Each system reflects over 20 years of racing expertise, including involvement in the Mini Challenge and BTCC. You’re not just installing parts—you’re soaking in race-tested technology.
Tailored Sound and Performance
From remote‑controlled valving to non‑resonated aggression and refined daily tones—Scorpion gives you emotion and function in one package.
Quality Construction & Materials
Built from T304 stainless steel and proactively acoustically tuned, these systems are both durable and beautifully engineered.
Modular Evolution
All components are engineered for interchangeability, allowing you to build your performance setup over time without compatibility headaches.

The Lineup at a Glance
1. TunR Non‑Resonated Cat‑Back System (SMNS033)
A bold upgrade engineered for volume and versatility. This system features 76 mm (3") piping with twin 100 mm tailpipes and a TunR active valve—so you can switch between a refined daily tone and a track‑ready roar using a wireless remote fob.
Available finishes include Daytona polished or ceramic, STW polished, and Ascari carbon fiber—each designed for style and long-term durability.
Key benefits: louder, aggressive tone, improved throttle response, weight reduction, and configurable sound.
2. Non‑Resonated Exhaust Suite for F56 Mini Cooper S & JCW 3‑Door (SMNS010)
A performance-focused, resonator-free system built with 2.75" pipework. It offers maximized airflow and tuning potential, courtesy of a thorough dyno and gas flow development program.
Highlights:
-
Optimal Performance: Balanced for driver enjoyment with a refined yet exciting sound. Interchangeable Design: Easily upgrade from OEM or past systems for modular tuning as your build evolves.
3. Mini Challenge Cat‑Back for Mini Cooper S F56 (SMN023 / SMNS023)

Constructed from 304 stainless steel, with 76 mm pipework and twin 90 mm polished tips. Features optimized rear silencers, improved gas flow, and sharper throttle response—giving that deep, resonant “race‑inspired” growl.
Seamlessly compatible with OEM or Scorpion downpipes for straightforward installation.
4. Downpipe with High‑Flow Catalytic Converter (SMNX021)
A high-performance downpipe for the F56 Mini Cooper S, featuring 63.5 mm (2.5") piping and a 200-cell sports catalyst to enhance flow and throttle response.
