Condition: Used for approximately 10k kms. No cracks, no leaks, no stripped threads. Flanges are flat and clean, cat substrate intact, no CEL at time of removal. Normal heat discoloration consistent with use — see photos.

Primaries were wrapped in titanium heat wrap by me. Wrap is used with some staining and light fraying but fully intact, secured with stainless ties.

Fitment: Toyota GR86 ZN8 and Subaru BRZ ZD8, FA24, 2021/10 onward. Direct bolt-on, no modification. Note: HKS lists fitment for manual transmission cars and has not confirmed compatibility with the automatic. Please verify against your own vehicle before buying.
