Korsh Unequal Length Headers for Subaru BRZ/Toyota 86 2012-2021

Korsh Unequal Length Headers — Subaru BRZ / Toyota 86 / Scion FR-S (2012–2021)

Korsh's unequal length headers for the 2012–2021 BRZ and 86 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 86 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 86 the noticeable, legendary BOXER RUMBLE.
