HKS GR86 Super Manifold with Catalyzer GT-SPEC

Introducing HKS' Super Manifold specifically for the Toyota GR86 and second-gen Subaru BRZ! Ditch weight and increase flow for enhanced performance and sound while staying emmissions legal.

• HKS employs a low-density metal catalyst compared to the factory ceramic catalyst with a high density. It drastically decreases exhaust resistance.
• It meets the emission control in Japan in 2018 by optimizing the blending ratio of the metals despite the low-density cells. Further, HKS obtains the certification for meeting the emission control from a third-party organization.
• 4-2-1 equal-length design layout. The complete equal-length layout is achieved by careful studying, especially for the 4-part sections.
• The flange at the cylinder head side employs the new design due to considering the structure of the stepped section when inserting the pipe.

"The above shows the output measurement result from the combined use of the manifold and the muffler. Output improvement is confirmed at the whole range when using the HKS Hi-Power SPEC-L2 and this product together. Mainly the difference is noticeable in the middle range. However, using this product and the Hi-Power SPEC-L2 together drastically eliminates decreasing the torque at around 4,000 rpm. Also, power output and torque are improved by a maximum of 10.2 kW (13.9 PS), 22.5 Nm (2.3kgf・m) at 4,300 rpm when combined with the GT manifold and Hi-Power SPEC-L2 compared to the factory vehicle." - HKS
