D Series Hood Exit Race Header

The 1320 Performance full race V2 hood exit header is engineered for D SERIES engines and D-series swapped classic vehicles, particularly those pre-1965. This header is purpose-built for drag racing applications where a straight header exit is utilized. It features a 4-to-1 tubing design with a specialized megaphone, which the manufacturer states enhances scavenging to boost both power and torque. Constructed from true 304 stainless steel, it incorporates a high-flow REAL merge collector and step primaries to further contribute to performance gains. The header comes with hardware for straightforward installation. Please note that minor leaks from the slip joint are considered normal, especially during cold starts, and can be resolved by having the joint welded at a local shop if desired. For applications using a 2-step launch control, it is crucial to add extra support from the bottom of the header to the block to prevent cracking due to extreme heat and vibration. WARNING: This product is intended solely for use on uncontrolled vehicles and for off-road or out-of-country use. It must never be used on any pollution-controlled motor vehicle.
