HKS Front Pipe w/High Flow Cat - Subaru BRZ ZD8/Toyota GR86 22+ 997 or other NPT-threaded componentsThe HKS stainless front pipe with high flow catalyzer is designed for the Toyota GR86 (ZN8) and Subaru BRZ (ZD8). It replaces the stock front pipe with a larger diameter stainless unit that includes an upgraded catalyzer and resonator silencer, improving exhaust flow while retaining a catalytic converter for road use. In flow bench testing it achieved 30% greater flow at 150L s compared to stock even with the catalyzer in place, and the combination of
