HKS 31029-AN011 Exhaust System Super Turbo Muffler for NISSAN Z (RZ34)

Description HKS 31029-AN011 Exhaust System Super Turbo Muffler for NISSAN Z (RZ34)

The HKS Super Turbo Muffler is engineered for the NISSAN Z (RZ34) to combine exhaust efficiency with reduced sound pressure, delivering a balanced system suitable for both stock applications and vehicles equipped with upgraded turbines. The design achieves a refined acoustic profile that complies with JASMA standards while preserving a distinctive tone developed specifically for the V6 engine.

A full dual layout with D60.5 mm × 2 piping increases the total cross-sectional area compared to the factory D45 mm × 2 configuration. This reduces exhaust pressure by approximately 40% while maintaining factory ground clearance, ensuring optimal flow without compromising daily usability. An optimized silencer structure and integrated silent chamber eliminate unwanted resonance during steady-state driving, while producing a sporty exhaust note under acceleration.
