Product Highlights

🎵 Engineered Sound Character – Powerful Yet Civilized
Developed using data from the GR Corolla and earlier GR Yaris, this muffler is tuned for the Gen2 platform. It suppresses unpleasant low-frequency drone and cabin resonance during normal driving, while delivering a rich, authoritative bass note and a clear sporty tone under acceleration. The result is a sophisticated sound profile that enhances the driving experience without compromising daily comfort.

⚡ Verified Performance Gains with Reduced Backpressure
This is not just a sound upgrade. Internal dyno testing confirms tangible performance improvements over the factory exhaust, with increased horsepower and torque and a significant reduction in exhaust backpressure, especially at higher RPM. This improved exhaust efficiency unlocks the engine’s breathing potential and provides a stronger foundation for future tuning.

🖤 Sophisticated URBAN MATTE Aesthetic
This edition distinguishes itself with a purposefully restrained, high-end finish:

• Matte Black Tailpipes: The 110mm dual tips feature a deep, matte black coating with a laser-engraved HKS logo for a stealthy, modern look.

• Hairline-Finished Silencer: The main muffler body boasts a precise hairline brushed finish, visible beneath the bumper, adding a touch of mechanical elegance.

• The overall design provides a “calming,” integrated appearance that complements the GR Yaris’s aggressive rear end without being ostentatious.

🔧 Gen2-Specific Engineering & Enhanced Durability

• Optimal Layout: Pipe routing, silencer placement, and pipe lengths are specifically configured for the Gen2 GR Yaris’s underbody, ensuring perfect fitment and optimal performance.

• Anti-Sway Kit: Includes a proprietary HKS rubber stay and special bracket to prevent lateral movement of the heavy muffler during aggressive driving, ensuring longevity and eliminating unwanted vibrations.

• Handcrafted Quality: The main muffler is meticulously TIG-welded and finished by hand, ensuring both structural integrity and visual perfection.
