The HKS Front Pipe is designed to improve exhaust flow and reduce overall weight compared to the factory component. Constructed from high-quality SUS304 stainless steel, it offers excellent durability, corrosion resistance, and a clean motorsport finish.
Flow bench testing shows up to a 30% increase in flow capacity at 150 L/s compared to the factory system, helping improve exhaust efficiency and engine performance. Despite the increased flow, the system is carefully tuned using frequency test data to maintain the iconic HKS exhaust sound while minimizing unpleasant drone or harsh noise inside the cabin.
The optimized combination of catalyzer and resonator silencer ensures a powerful exhaust note without discomfort during driving, even when paired with other HKS exhaust components such as the HKS exhaust manifold and Hi-Power Spec L exhaust system.
