Crafted from high-silicon molybdenum (hi-sil moly) iron, these manifolds are engineered to enhance your vehicle's performance by optimizing power and flow dynamics. The entire exhaust system is meticulously designed to lower exhaust gas temperatures (EGTs), boost turbo spool-up, and improve overall power output and fuel efficiency, all while maintaining superior reliability.
Key Features:
- Significant Reduction in Back Pressure: Improves exhaust flow for better performance.
- High-Flow Manifold Construction: Made from durable cast hi-sil moly iron for maximum strength and longevity.
- Sensor Compatibility: Built-in bosses pre-drilled and tapped with 1/8” NPT fittings, ready for easy installation of an EGT gauge sensor.
