GT86 HKS Super Manifold with Catalyser Boxer Spec

4-1 Design - Unequal Length - With Cat

60mm pipe diameter

The HKS 4-1 manifold is un-equal length and produces more power in the mid range along with the "boxer sound".

With tuning this manifold can significantly reduce the "torque dip" associated with the stock manifold.

Includes alloy bungs to delete noise generator

Fensport Tip: For the best result, Ecu will require tuning, we recommend our GT86 & BRZ NA Remap for maximum power gains.
