HKS 32025-AT002 Super Exhaust System - Super Manifold R-Spec with Legamax Sports

The HKS 32025-AT002 Super Exhaust System is a complete manifold-back exhaust solution combining two purpose-engineered components: the Super Manifold with Catalyzer R-Spec and the Legamax Sports muffler system. Together, they form a cohesive, performance-tuned exhaust package designed to improve throttle response, reduce exhaust back pressure, and deliver a refined, sporty exhaust note — all while meeting Japanese safety and emissions standards.

The Super Manifold with Catalyzer R-Spec features a straight-pipe exhaust manifold and front pipe equipped with an HKS Metal Catalyzer, engineered for an optimized flow layout. The Legamax Sports muffler is purpose-built to simultaneously reduce sound pressure levels and minimize exhaust back pressure, striking a balance between performance and daily drivability.

Key Features:

• 4-2-1 exhaust manifold design significantly improves drivability and torque response in the 3,000 RPM range
• HKS Metal Catalyzer reduces pressure loss at high RPM for improved power delivery and throttle feel
• Legamax Sports muffler balances low sound pressure with reduced back pressure for a refined yet sporty exhaust note
• Straight-pipe manifold with integrated front pipe designed for ideal exhaust gas flow and layout efficiency
• No vehicle modifications required for installation — bolt-on fitment with an estimated installation time of 1–2 hours on a cold vehicle
• Japanese safety standard compliant — includes Emission Test Certificate for verified regulatory compliance

An ideal upgrade for enthusiasts seeking a complete, certified exhaust system that improves both performance and sound quality without sacrificing daily usability or regulatory compliance.
