BMW M3/M4 (G80/G82) - Catless Downpipes

The silencing effect of the converters are also removed, enhancing the aggressive engine sound. Test pipes are ideal for track days and race application.

On applicable models, the center section is made flexible as an added protection feature against vibration damage to the header pipes and the Lambda or Oxygen Sensor Bungs are pre-installed and threaded.

Made from T309 (1.4828) stainless steel.

IMPORTANT:

*Designed and Recommended For Off-Road and Track Use Only*

Modifying Your OEM Catalytic Converter/s may trigger a CEL (Check Engine Light).

To disable a recurring CEL you will need to tune the ECU.
