Free the Flow of Your GR Supra 3.0
The factory downpipe is one of the first restrictions after the turbocharger. This Flashark catless downpipe is designed as a direct-fit upgrade for selected 2020–2024 Toyota GR Supra models equipped with the 3.0L turbocharged B58 inline-6 engine.
Its free-flowing catless design helps reduce exhaust restriction after the turbo, making it an ideal supporting upgrade for enthusiasts building a more responsive, more aggressive-sounding B58-powered Supra.
Built Specifically for the 3.0L B58 GR Supra
- Vehicle-Specific Fitment: Designed for confirmed 2020–2024 Toyota GR Supra 3.0L turbocharged B58 applications.
- Catless Free-Flow Design: Replaces the restrictive factory catalytic-converter section with a more direct exhaust path.
- Direct-Fit Upgrade: Designed to install in the factory downpipe location on confirmed applications.
- More Aggressive Exhaust Character: Helps deliver a louder and more pronounced turbocharged exhaust tone.
- Built for Performance Projects: A strong supporting modification for customers planning compatible exhaust and calibration upgrades.
Important: This product fits the 3.0L turbocharged B58 GR Supra only. It does NOT fit Toyota Supra 2.0L 4-cylinder models.
Performance results, warning lights, and calibration requirements vary by vehicle configuration and local regulations.
