GDB HKS Silent Hi Power Exhaust – 04/06~ (Require HKS Front Pipe for UK car)

Impreza GDB HKS Silent Hi Power Exhaust 【silent Hi-Power】 High-quality sound. Sports exhaust system with the reduced noise level. 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 removes a lot of the lower frequency noise that can often be heard into the cabin even when cruising. The silent chamber removes 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.
