Authentic HKS Stainless Steel Equal Length Exhaust Manifold 2006-2014 WRX / 2004-2021 STI

Description

This tubular turbo exhaust manifold is engineered to maximize exhaust flow, improving turbo spool-up and providing exceptional flow capacity. Constructed from durable SUH409 stainless steel, it’s built to withstand high temperatures while delivering long-lasting performance.

By upgrading to this manifold, you’ll experience enhanced throttle response and a more aggressive exhaust tone thanks to its isometric layout. The improved flow makes the engine feel more responsive, giving the driver greater control and a sharper driving experience.

Please note that HKS does not include an uppipe with this manifold, and it is designed to be used with a factory-style 2-bolt uppipe. This header fits any turbo Subaru model equipped with a triangle-style oil pan; however, 2002-2005 WRX owners will need to convert to an STI oil pan for proper installation.
