Korsh Unequal Length Headers for Subaru BRZ/Toyota GR86 2022+

Korsh Unequal Length Headers — Subaru BRZ / Toyota GR86 (2022+)

Korsh's unequal length headers for the 2022+ BRZ and GR86 platform are engineered to optimise exhaust flow dynamics through precisely calculated runner lengths. The staggered tube configuration minimises overlap losses and maximises scavenging efficiency — delivering tangible gains in mid-range torque and peak horsepower. As a bonus, the unequal length design produces the distinctive, legendary boxer rumble that BRZ and GR86 owners love.

Constructed from 304 stainless steel with cast flanges for a perfect, leak-free fit, these headers are built to handle sustained high-temperature operation in both street and track environments. Every kit ships complete with all gaskets and hardware — ready to bolt on straight out of the box.

⚠️ WARNING: This will give your Subaru BRZ / Toyota GR86 the noticeable, legendary BOXER RUMBLE.
