The Front Pipe Standard TF3181 is a motorsport-specific, straight-through stainless steel pipe engineered to replace the restrictive OEM secondary catalytic converter on the Toyota GR86 and Subaru BRZ (FA24).

Designed exclusively for competition use, this critical component significantly reduces exhaust backpressure at the primary stage, unlocking improved engine response and increased power potential for tuned, track-focused applications.

Product Highlights

🏁 COMPETITION-ONLY DECAT DESIGN
This front pipe is a direct, non-catted replacement for the factory secondary catalytic converter. Its straight-through, competition-only design is not legal for public road use, providing the unrestricted exhaust flow essential for maximum performance in closed-course environments.

📈 OPTIMIZE PRIMARY EXHAUST FLOW
By eliminating the secondary catalytic converter located immediately after the exhaust manifold/header, this pipe drastically reduces initial exhaust restriction. This allows for faster evacuation of exhaust gases, contributing to improved throttle response, enhanced top-end power, and more efficient turbo or supercharger integration in forced-induction setups.

🔧 DIRECT FIT FOR THE FA24 PLATFORM
Engineered as a direct bolt-on component that connects the exhaust manifold or aftermarket header to the center pipe.

• Compatible with: All standard Toyota GR86 (RZ, SZ, RC) and Subaru BRZ (R, S, STI Sport)* models.
  *Excludes BRZ Cup Car Basic and STI Sport TYPE RA.

⚖️ SIGNIFICANT WEIGHT REDUCTION
Crafted from high-quality stainless steel, this single-piece front pipe offers a substantial weight reduction over the heavier, restrictive OEM unit, contributing to overall vehicle weight savings.

• Unit Weight: 3.0 kg (OEM Reference Weight: 5.6 kg)

• Weight Saved: ~2.6 kg (Approximately 46% reduction)
