Item number: 33004-BT003

Maximum flow, street-legal performance and top Japanese quality – the ultimate upgrade for your FA24.

The HKS Stainless Front Pipe with Sport Cat (33004-BT003) has been specially developed for the Toyota GR86 and Subaru BRZ FA24 (2021+). This high-quality stainless steel front pipe replaces the restrictive OEM pipe and features a high-flow sport catalyst, significantly improving both exhaust gas flow and performance, without compromising emission standards or usability.
