Description: HKS Hi-power Catback Exhaust

Fitment: 02-07 Subaru WRX / STI

Details:

High-quality sound. Sports exhaust system with 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.

Details:

• 120mm Polished Tip

• 92 Decibels

• SUS304 for improvement of appearance and durability.

Note: A OEM Downpipe to 3in Cat Back Adapter may be necessary if the diameter of the new cat-back exhaust systems piping is different from the stock system, or if there are compatibility issues between the new components and the existing downpipe.
