HKS has uniquely designed the Silent Hi-Power Dual Exhaust for specific vehicle models to optimize the straightest flow pipe according to vehicle. Optimized piping for each vehicle model to ensure the straightest flowing piping possible. Enjoy the full sound of the engine with increased piping diameter, up to 3.5 inches. Very competitive pricing due to the use of SUH409 piping. Silent Hi-Power mufflers offer high performance and sporty appearance with the added benefit of reduced noise levels making it the best choice for more mature enthusiasts. Silent Hi-Power mufflers are constructed entirely of SUS304 grade stainless steel for high luster, long-lasting performance. For certain applications, HKS has introduced the "Silent Chamber" which eliminates a lot of the lower frequency noise that can often be heard into the cabin even when cruising. The silent chamber eliminates this uncomfortable noise but due to its closed-end design, only a minimal amount of exhaust gas flows into it, meaning that the disruption to exhaust gas flow through the entire system is minimized and there is no harm to performance. The straight structure has the characteristic that is easy to eliminate high-frequency sound. However, it is difficult to control the low-frequency uncomfortable sound that can be heard in the cabin. A silent chamber can reduce this low sound. In addition, because of the closed inside structure, exhaust gas does not through the inside silent chamber and exhaust gas resistance is less. Therefore, there is no performance difference even silent chamber is equipped.
