Description
Toyota GR Yaris (Gen 2) - GPF/OPF Bypass
Product Overview
This Milltek Sport downpipe upgrade is designed for the Toyota GR Yaris (Gen 2) in the GPF/OPF Bypass configuration. The larger, freer-flowing exhaust path is intended to reduce restriction in the front section of the exhaust and is particularly suited to performance-focused vehicles and supporting engine software where required.
Product Details
As the GPF/OPF almost acts as a secondary catalyst, we have provided the option to remove this component, similar to a Decat system. This bypass deletes the GPF/OPF, removing it from the exhaust system to better improve performance.
Introduced in 2024 the Mk2 Yaris builds on the success of its predecessor, with several enchancments at improving performance, handling and driver engagement, we decided to give it the Milltek touch with a GPF/OPF bypass to improve airflow, and can greatly increase sound dynamics.
