Scorpion GPF Back Exhaust System For BMW F70 M135 xDrive

Upgrade the sound and presence of your BMW M135 with the Scorpion GPF-Back Exhaust System, engineered specifically for 2024–2026 models. Designed to replace the restrictive rear section of the factory exhaust while retaining the petrol particulate filter (GPF), this system delivers a deeper, more purposeful exhaust note while maintaining compatibility with the original emissions equipment. Manufactured in Derbyshire, UK using premium materials and precision fabrication, this Scorpion exhaust offers a high-quality upgrade for drivers looking to refine the sound and character of their M135.

Precision-Engineered Stainless Steel Construction

The Scorpion GPF-back system is manufactured using T304 motorsport-grade stainless steel, chosen for its strength, corrosion resistance and long-term durability. The system features a 70mm (2.75") pipe diameter, optimised to support improved exhaust flow while maintaining excellent refinement for everyday driving.

Each system is designed and manufactured in the UK using advanced fabrication techniques and strict quality control standards, ensuring consistent performance and reliable fitment.

Retains the Factory GPF

This exhaust is designed as a GPF-back system, meaning it replaces the rear section of the exhaust while keeping the factory GPF in place. This allows owners to enhance the exhaust tone and appearance of the vehicle while maintaining compatibility with the original emissions components.

The result is a more engaging exhaust character that complements the M135’s turbocharged engine without overwhelming everyday usability.

Tailpipe Options

This Scorpion system is available with a choice of quad tailpipe finishes, allowing you to tailor the final appearance to suit your BMW’s styling:

• Polished Daytona – Classic stainless steel finish with a bright, clean appearance

• Black Ceramic Coated Daytona – Stealth-inspired black finish for a more aggressive look

• Carbon Fibre Ascari – Premium carbon fibre outer sleeve with distinctive performance styling

Each option provides a distinctive rear-end finish while maintaining the signature Scorpion design.
