HKS Hi-Power Muffler Spec-L II Honda S660 JW5
Unlock sharper sound, reduced weight, and genuine motorsport quality for your Honda S660 with the HKS Hi-Power SPEC-L II. Designed specifically for the JW5 platform, this high-performance exhaust system delivers an exhilarating tone while maintaining excellent drivability and comfort for daily use.
Crafted from lightweight S304 stainless steel, the Spec-L II significantly reduces weight compared to the factory system—improving throttle response and overall vehicle dynamics. Dual 75 mm tips give the S660 a clean, performance-focused appearance, while the straight-through layout enhances exhaust flow for improved turbo efficiency.
Engineered and tested by HKS in Japan, this system is fully compatible with both 6-speed manual and CVT models, including vehicles equipped with Modulo X or Mugen rear bumpers. Despite its sportier character, noise levels remain well-controlled, offering a refined exhaust note without excessive drone.
Perfect for drivers seeking a premium, lightweight, and beautifully tuned exhaust upgrade, the HKS Hi-Power SPEC-L II enhances both the look and feel of the S660 without compromising everyday usability.
