Product Description

The HKS G89580-T76010-00 Error Cancellation Kit is a critical accessory for owners of 2022-2025 Toyota GR Corolla who wish to install an aftermarket exhaust system without triggering check-engine lights or exhaust-system fault codes. Because modern vehicles monitor exhaust back-pressure, oxygen sensors, and catalytic converter efficiency, replacing or upgrading the exhaust can often lead to persistent warning codes or ECU-flagged errors. This HKS kit intercepts or corrects the signals to maintain the ECU's "happy" state, allowing you to enjoy upgraded exhaust performance smoothly and cleanly.

Installation is designed to be simple and plug-and-play, requiring no ECU re-flash or complex wiring work - ideal for enthusiasts who want to keep modifications reversible or maintain warranty-friendly status when possible. Whether you're installing a full cat-back exhaust, a performance muffler, or other exhaust upgrades on a GR Corolla, pairing that exhaust with G89580-T76010-00 helps ensure a clean, error-free driving experience.
