HKS Super Manifold with Catalyzer GT-SPEC - Toyota GR86 / Subaru BRZ 22+

The HKS GT-Spec Super Manifold with Catalyzer for the 22-23 BRZ and GR86 features an equal length exhaust manifold and a low-density metal catalyst compared to the high-density factory ceramic catalyst to drastically decrease exhaust resistance and optimize flow.

• GT-Spec Catalyzer improves exhaust flow
• 4-2-1 equal-length design creates less pressure and increases efficiency
  
• Compact yet better purifying catalyzer allows for lower emissions and clears the strict Japan Exhaust Gas Regulation
• Improves power output
• Increases torque
