Description

These shorty headers are designed to improve exhaust flow, increasing horsepower and torque. They are made from stainless steel for durability and corrosion resistance. They are a direct bolt-on replacement for the factory manifolds. They feature mandrel-bent stainless steel primary tubes for optimal flow, durability, and improved throttle response. The patented JBA Firecone collector is race-proven technology for maximum horsepower and torque gains. The system includes high-quality hardware and thorough instructions for a professional, no-leak installation. It also includes factory-style emission connections for easier installation and is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide (CARB Executive Order (EO) number D-57-33).
