Our BMW X4 Series Performance Exhausts are developed for the G02 X4M and X4M Competition (2022-2026). These freer-flowing Milltek Sport systems utilise 115mm tips and offer modular secondary catalyst bypass options to reduce backpressure and maximise the output of the S58 straight-six engine.

• LCI Systems: Primary cat-back and axle-back setups with Titanium, Carbon, or Cerakote Black trims providing a freer-flowing exhaust path.
• Secondary Cat Bypass: Dedicated bypass sections for improved, freer-flowing performance (requires OE system cutting on specific fitments).
• OPF/GPF Solutions: Filter-back systems designed to reduce backpressure while awaiting TUV testing for European compliance.
