HJS ECE Downpipe, Toyota Yaris GR XP21 1.6L (261HP)

A high-performance HJS downpipe designed to replace the original, restrictive downpipe in the Yaris GR while preserving road-legal ECE certification.

This free-flowing performance downpipe typically lowers exhaust gas temperatures and reduces turbocharger stress due to decreased back pressure. These improvements enhance spool-up and overall performance, benefiting both stock and especially tuned engines.

Performance Gains: up to +10 HP and +10 Nm torque without software modifications; gains are even more pronounced in tuned engines.
