Description
The 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 catalyzer and resonator tuning eliminates unwanted blat and drone noise when paired with performance manifold and muffler combinations.
Features
- 60mm pipe diameter vs smaller stock pipe
- 30% flow improvement over stock in bench testing at 150L/s
- High-flow catalyzer retained - road-use compatible
- Resonator silencer tuned using frequency analysis to eliminate blat and drone
- Lightweight SUS304 stainless construction: 3.3kg vs stock 5.5kg
- Minimum ground clearance 120mm (at center pipe)
