Scorpion BMW M135i (F70) GPF Delete
The Scorpion GPF Delete for the BMW M135i (F70) replaces the factory Gasoline Particulate Filter (GPF) with free-flowing pipework. It is aimed at drivers who want a stronger exhaust sound and less restriction for tuning.
What is a GPF delete and why consider it?
The GPF is a filter in the exhaust system that traps tiny soot particles from the petrol engine. While it helps reduce emissions, it also:
- Reduces exhaust noise and character
- Adds back pressure, which can limit power and response
- Restricts airflow, which can hold back tuning gains
A GPF delete removes this filter and replaces it with smooth, straight-through pipework. This improves exhaust flow and lets the engine breathe more easily.
Main benefits
Fitting the Scorpion GPF Delete to your BMW M135i can offer:
- A louder, more aggressive exhaust note with more turbo noise
- Reduced back pressure for sharper throttle response
- Improved potential for performance tuning via ECU software
On a standard car you will mainly notice the change in sound and a more responsive feel. Any significant power gains usually come when the GPF delete is combined with a remap and other supporting parts, such as a sports cat or full performance exhaust system.
