Price range: £1,951.41 through £2,239.39
Scorpion BMW M135i (F70) GPF-Back Exhaust System
The Scorpion GPF-back exhaust for the BMW M135i (F70) is crafted to enhance sound and improve exhaust flow while integrating seamlessly with the factory GPF (gasoline particulate filter). This system replaces the pipework and rear silencers from the GPF back, ensuring that all factory sensors remain intact.
What this exhaust does
This exhaust system features 70 mm pipework that leads to quad 100 mm circular tailpipes. The benefits include:
- Larger bore and smoother bends facilitate better airflow and reduce back pressure.
- Improved throttle response and more engaging sound, particularly advantageous for tuned vehicles.
- Smoother power delivery, especially during spirited driving.
As a GPF-back system, the GPF itself stays in place, providing several advantages:
- No alteration to the GPF or primary emissions components.
- Lower risk of warning lights compared to more invasive exhaust modifications.
- A sound upgrade that feels sportier without being too loud for everyday driving.
Fitment and compatibility
This Scorpion GPF-back exhaust is specifically designed for the BMW M135i (F70) with the factory GPF system. It fits perfectly with the standard rear bumper and uses original mounting points, typically requiring no cutting or significant car modifications. To ensure compatibility, please use the vehicle lookup tool on the site or check the Vehicle Fitment tab for full details.
Tailpipe options
Choose from three distinct Daytona tailpipe finishes to match your vehicle’s aesthetic:
- Polished Daytona (SKU: SBMS117) – High-grade T304 stainless steel with a bright, mirror-like finish.
- Ceramic Black Daytona (SKU: SBMS117C) – Matte black finish that is heat resistant and durable.
- Carbon Fibre Ascari (SKU: SBMS117CF) – A modern touch adding a sporty flair.
All options maintain the 100 mm diameter and quad layout, delivering a purposeful, motorsport-inspired look.
Why choose this system
The Scorpion GPF-back exhaust is an excellent choice if you seek to enhance the sound and character of your BMW M135i while keeping the core emissions components unchanged. You can anticipate:
- A deeper, sportier tone compared to the factory exhaust.
- More presence under load and during boost, yet not excessively loud during regular driving.
- High-quality construction using T304 stainless steel for enduring performance.
- A choice of tailpipe finishes to complement your vehicle’s style.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
