SSXTY119 80 mm Race Front Pipe for BMW M340i xDrive G20 B58 and Toyota GR Supra A90 3.0 B58

Unleash the B58’s true character with Milltek Sport’s large diameter turbo outlet front section. This straight-through primary catalyst delete is designed for OPF and GPF equipped cars, delivering freer flow, a harder-edged soundtrack and rapid spool when combined with a Stage 2 remap. If you want serious gains in response and a more aggressive tone from your M340i xDrive or Mk5 Supra, this is the hardware to start with.

Why enthusiasts choose SSXTY119

  • 80 mm 3.15 inch tubing lowers back pressure so the B58 breathes better for stronger mid-range and top-end.
  • De-cat race pipe for closed-course and off-road motorsport only.
  • Noticeably quicker boost build, sharper throttle feel and a deeper, richer note under load.
  • Built in the UK with OE-style hangers for a secure, direct install on OPF/GPF-equipped vehicles.
  • Exact part number: SSXTY119.

Proven on cars we build

We have fitted this Milltek front section to customer M340i and GR Supra projects, and feedback is consistently excellent. Expect faster spool, a more engaging exhaust character and a freer-revving feel that transforms day-to-day driving and pairs perfectly with a Stage 2 calibration.
