Dual-Personality Sound Control
Featuring our advanced valve technology, this system allows you to transform your driving experience at the touch of a button. Tested and recorded with the Max Racing Catted Downpipe and Catless Frontpipe, experience a 30dB shift in personality at the click of a button:
Valve ON (Sport Mode): A raw, loud sporty tone hitting 100dB. Perfect for the track or spirited canyon runs where you want every shift to roar.
Valve OFF (Street Mode): A refined, deep bass tone at a comfortable 70+dB. Designed for daily commuting without sacrificing the signature GR character.
Specifically tuned to cancel out the “booming” frequencies common in the GR Yaris cabin between 3,000 – 4,000 RPM.
Performance & Engineering
Zero Drone Technology: Meticulously tuned to eliminate cabin drone, ensuring a premium interior experience even at cruising speeds.
Full 3-Inch (76mm) Flow: Unlike standard 2.5″ upgrades, our upsized 3-inch piping eliminates backpressure, allowing the turbo to spool faster and hold boost more efficiently at high RPMs.
Versatile Fitment: This system is a direct-fit masterpiece, compatible with both the Max Racing Frontpipe and the Stock Frontpipe, allowing for a modular upgrade path.
Premium Construction: Built with high-grade stainless steel for durability and heat resistance under extreme conditions
🏁 Proven Across Three Environments
We don’t just claim gains; we prove them. This system has been rigorously tested as a complete flow solution (Intake + Downpipe + Catback):
On the Dyno: Significant Wheel Horsepower (WHP) and Torque gains recorded on the chassis dynamometer compared to the stock restrictive 2.5″ system.
- On the Street: Refined daily drivability with Zero Drone technology. The valve-closed mode keeps sound at a civil 70+dB.
