Description

The HKS Super Sound Master represents a sophisticated exhaust system specifically engineered for the Honda S2000 (AP2 chassis, 2005-2009 models) that masterfully balances authentic acoustic enhancement with refined power delivery and aesthetic integration.

Designed not merely for increased volume but for superior sound quality, this system delivers the distinctive, high-revving character inherent to the F22C engine while maintaining street-appropriate noise levels and seamless visual integration with the S2000’s rear design.

Through its precision mandrel-bent S304 stainless steel construction and optimized RS-style muffler configuration, this exhaust provides a transformative auditory experience that complements the S2000’s sporting pedigree without compromising daily usability or violating sound regulations in controlled environments.

Product Highlights

🎵 Authentic Acoustic Enhancement, Not Mere Volume Increase
Engineered specifically to refine and elevate the F22C engine’s inherent acoustic character, the Super Sound Master prioritizes tone quality and harmonic richness over simple decibel increase.

With certified sound levels of L91/R92 dB during proximity testing—only slightly reduced from the factory 95 dB—this system delivers noticeable enhancement while remaining within reasonable street parameters and track day noise restrictions.

🔧 Precision S304 Stainless Steel Construction for Durability & Performance
Utilizing premium S304 stainless steel throughout its mandrel-bent piping and RS-style muffler construction, this system ensures long-term corrosion resistance while maintaining optimal exhaust gas flow. The dual 60-50mm intermediate piping configuration (representing the widest sections excluding shell and tail diameters) provides balanced flow characteristics that support natural engine breathing without creating excessive backpressure.

🎯 AP2-Specific Engineering for Seamless Integration
Designed exclusively for the 2005-2009 AP2 chassis S2000, this system accounts for the specific underbody geometry and mounting points of later model years. With a ground clearance specification of 123mm at the exhaust’s lowest point (measured on standard suspension), it maintains practical usability while accommodating mild lowering without significant interference risks.

📜 Certified Compliance & Measured Performance
Carrying certification number 03S15773, this exhaust system meets established regulatory standards while providing documented performance characteristics. The precise engineering extends to weight optimization—though specific figures aren’t published—ensuring the system doesn’t introduce unnecessary mass that would compromise the S2000’s renowned balance and responsiveness.

Performance & Engineering Philosophy

Goal: To enhance the S2000 driving experience through refined acoustic improvement that respects the engine’s inherent character while providing durable construction and seamless integration—creating an exhaust system that feels like a natural evolution of the factory design rather than an aftermarket addition.

Focus: Authentic sound quality enhancement through tuned resonance and flow characteristics; premium material selection for longevity and consistent performance; model-specific engineering for optimal fitment and ground clearance; and certified compliance that ensures usability in controlled environments with noise restrictions.

Installation & Application Considerations

🔧 Professional Installation Recommended
While designed for direct replacement, proper installation requires careful alignment to ensure optimal ground clearance and prevent contact with underbody components, particularly if the vehicle is equipped with lowering modifications.

⚠️ Critical Fitment & Usage Notes:

• Ground Clearance Variance: The published 123mm clearance represents the exhaust system specifically, which may differ from overall vehicle clearance depending on suspension modifications and driving conditions

• Suspension Modification Effects: While tested with some lowering configurations, significant suspension alterations may require additional clearance verification

• Component Evolution: Mounting hardware including hooks, brackets, and stays may undergo revision without notice as part of continuous improvement

• Sound Level Context: The certified sound levels represent controlled measurements that may vary with engine modifications, driving conditions, and measurement methodologies

🎯 Primary Performance & Experience Benefits:

• Acoustic Enhancement: Refined exhaust note that emphasizes the F22C’s high-RPM character without excessive volume

• Flow Optimization: Balanced piping dimensions that support natural engine breathing without restrictive backpressure

• Visual Integration: RS-style muffler and 102mm tailpipes that complement the S2000’s rear design aesthetic

• Quality Construction: S304 stainless steel ensuring longevity and consistent performance across temperature cycles

Strategic Advantages & Design Rationale

🔊 Measured Acoustic Development
The deliberate sound level target—slightly reduced from factory while delivering enhanced quality—demonstrates sophisticated acoustic engineering focused on refinement rather than mere amplification, appealing to enthusiasts who value driving experience over attention-seeking volume.

⚙️ Model-Specific Rather Than Universal Design
By engineering specifically for the AP2 chassis rather than offering a universal fitment, HKS ensures optimal ground clearance, mounting integrity, and aesthetic integration that universal systems cannot achieve, reflecting understanding of the S2000’s precise engineering parameters.

📏 Transparent Performance Documentation
The publication of certified sound levels, specific dimensions, and clearance data provides realistic expectations rather than marketing generalizations, allowing informed purchase decisions based on documented characteristics rather than subjective claims.
