HKS- SUPER MANIFOLD with CATALYZER GT-SPEC TOYOTA GR86 ZN8

■FEATURE

• 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.
