2003-2009 Subaru Legacy B4 HKS Silent Hi-Power Exhaust System

HKS Silent Hi-Power Exhaust system for 2003-2009 Subaru Legacy B4. The Silent Hi Power exhaust system is perfect for those who want the performance sound, but only at high RPM. Made with SUS304 grade stainless steel, the Silent Hi Power exhaust system provides maximum exhaust flow, a high shine finish and extreme durability. By integrating a "Silent Chamber" within the exhaust system, low level frequency noises are scaled down. This dramatically reduces constant exhaust noise within the vehicles cabin at cruising speed without affecting performance or exhaust flow. At high rpm on the other hand, users will experience a much higher performance tone.

The Silent Hi Power exhaust system is an excellent upgrade for performance enthusiasts looking to increase power, exhaust flow, and a deep performance growl while eliminating the droning noise at low rpm. HKS is an extremely reputable company that produces high quality performance products imported directly from Japan. Their products are a favorite amongst performance enthusiasts worldwide. Produced with high quality stainless steel, their exhaust systems are durable and maintain a high shine appearance.
