The HKS GT-SPEC 4-2-1 Exhaust Manifold with Catalytic Converter is designed for the Toyota GT86 and Subaru BRZ (2012-2019) equipped with a manual transmission. This vehicle-specific exhaust manifold is engineered to improve exhaust flow, reduce back pressure, and enhance overall engine performance. As part of the HKS GT-SPEC range, it is developed for enthusiasts seeking increased performance while maintaining effective emissions control.

The optimised 4-2-1 header design maximises exhaust pulse scavenging for improved performance across a wide RPM range. HKS has redesigned both the manifold layout and the integrated high-flow catalytic converter to reduce exhaust restriction, resulting in quicker throttle response, improved mid-range torque, and enhanced power delivery from low to high engine speeds. Despite its compact design, the catalytic converter complies with Japanese emissions regulations thanks to its advanced catalyst material.

Manufactured from SUS304 stainless steel, the manifold offers outstanding corrosion resistance, excellent heat resistance, and long-lasting durability, making it ideal for demanding street and track use. Its vehicle-specific design ensures direct bolt-on installation with OEM-style fitment, requiring no modifications.

In October 1973, two talented and young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not, or would not, produce. HKS pioneered the Japanese aftermarket industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back ECUs and sophisticated fuel management tools. HKS was clearly driving performance trends for Japanese vehicles forward!

Today, HKS is one of the world's most well-known brands and the obvious choice for you who builds a JDM car. In the assortment you will find everything from chassis products to exhaust systems and turbo kits. HKS is behind some of the coolest builds and professional drivers in the world, so when you choose HKS, you choose the best.
