Silent Hi-Power mufflers deliver a perfect blend of high performance and sporty aesthetics, while significantly reducing noise levels, making them the ideal choice for more refined enthusiasts. Constructed entirely from SUS304 grade stainless steel, they ensure a high-luster finish and long-lasting durability. For certain models, HKS has incorporated a "Silent Chamber" to eliminate lower-frequency noise often heard inside the cabin, especially while cruising. The chamber reduces this discomfort without compromising performance, as its closed-end design allows minimal exhaust gas flow disruption, ensuring smooth operation and maintaining optimal exhaust efficiency.
