Product Highlights

PURE COMPETITION-SPECIFICATION DESIGN: This product is engineered and classified “For Competition Use Only”. It is not JQR-certified and is explicitly not legal for use on public roads. It produces high sound levels measured at 96 dB (6MT) / 105 dB (8AT) under acceleration, providing the intense, raw acoustic feedback desired for motorsport applications. A dedicated competition product purchase application is required.

DRAMATIC WEIGHT REDUCTION FOR PERFORMANCE GAINS: Engineered with performance as the priority, this muffler achieves a substantial weight reduction of 6.7 kg compared to the stock exhaust (7.6 kg vs. 14.3 kg). This reduction in unsprung mass can contribute to improved handling response and acceleration.

DIRECT FIT FOR 2024+ GR YARIS MODELS: Designed as a bolt-on replacement for the rear muffler section of the latest GR Yaris (4BA-GXPA16 platform). It is compatible with both 6-speed manual (6MT) and 8-speed automatic (8AT) transmissions, fitting all RZ grades (including high-performance editions) and RC models manufactured between April 2024 and May 2025.

HIGH-FLOW STAINLESS STEEL CONSTRUCTION: Fabricated from high-quality all-stainless steel for durability in demanding conditions. The system features a straight-through 70mm diameter pipe for minimal flow restriction and terminates in a single 90mm slash-cut tip exiting on the right side. The kit includes all necessary mounting hardware and a specific bracket kit (STF.KIT58) for a secure installation.
