High Flow Engineering B58 Decat Downpipe Non-OPF Performance Upgrade

Unleash the true performance of your Toyota Supra A90 / A91 B58 Non-OPF with the HFE Heat-Shielded Decat Downpipe. Designed to replace the restrictive factory catalytic converter section, this high-flow decat significantly reduces exhaust backpressure, enhances turbo response, and supports increased power output on tuned vehicles - making it a core upgrade for serious B58 builds.

⚠ IMPORTANT – EMISSIONS & ROAD USE NOTICE

This product removes the factory catalytic converter and is intended for off-road, motorsport or track use only. It is not UK road legal and will likely result in an MOT emissions failure. ECU tuning is required after installation.

Key Features＋
  • High-Flow Decat Design: Eliminates the restrictive OEM catalytic section.
  • Integrated Heat Shielding: Reduces surrounding engine bay temperatures.
  • Improved Turbo Efficiency: Faster spool and sharper throttle response.
  • Performance 304 Stainless Steel Construction: Built to withstand extreme exhaust temperatures.
  • Mandrel-Bent Tubing: Smooth internal flow for reduced turbulence.
  • Direct-Fit Installation: Designed for Non-OPF B58 Supra models.
Why Upgrade Your A90/A91 Downpipe?＋
  • The factory catalytic converter is a significant restriction on tuned B58 engines.
  • Reduced backpressure improves overall engine efficiency.
  • Essential supporting modification for Stage 2 tuning.
  • Enhances exhaust tone and turbo sound characteristics.
  • Improves power delivery under high load.
Technical Specifications＋
  • Engine: BMW B58 3.0L Turbo
  • Vehicle: Toyota Supra A90 / A91
  • Configuration: Decat (no catalytic converter)
  • Shielding: Integrated heat shielding
  • Material: High-grade stainless steel
  • Fitment: Non-OPF models only

✔ Always confirm model specification before ordering
✔ ECU tuning required

Installation＋
