Sound options explained
- Resonated: Includes a centre silencer for a refined yet sporty note.
- Non-Resonated: Louder, more raw tone. This is the sportier, more vocal option.
- Valved: Retains exhaust valves. Switching drive modes continues to change the tone from quieter to louder as before.
- Non-Valved: Removes exhaust valves. Sound does not change with drive modes. No harm to running, just a fixed, carefully tuned Cobra sound.
Tailpipe options
- TP19 – 4.5 inch Chrome Tailpipe
- TP38 – 4 inch Chrome Inverted Tailpipe
- TP106-CF – 4.5 inch Slash Cut Carbon Fibre Tailpipe
- TP107-CF – 4 inch Slash Cut Carbon Fibre Tailpipe
Compatibility
BMW 1 Series F40 (2019+): M135i xDrive / M135ix
Note: Fitment is for motorsport and off-road use only where the system removes the PPF. Mandatory ECU recalibration is required when fitted to PPF models to cancel the EML.
Back box delete systems without a rear silencer will be extremely loud.
