HKS Toyota GR86 ZN8 FA24 Super Manifold w/ Catalyzer GT-SPEC
hks33005-AT010
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.
