Description

Upgrade your Ford Mustang with the JBA Tri Y Header designed specifically for models from 1967 to 1970 equipped with 390-428 FE engines. These long tube headers are engineered to maximize performance, delivering significant horsepower and torque gains across the entire RPM range. Constructed from high-quality stainless steel, available in either 409 or 304 series, they feature large mandrel-bent primary tubes for smooth exhaust flow and enhanced engine efficiency. The proprietary JBA Firecone® merged collectors optimize scavenging and reduce backpressure, resulting in improved throttle response and overall power output. The headers include oversized exhaust ports and extra thick 3/8-inch CNC laser-cut flanges for durability and a secure fit, ensuring long-lasting performance. Designed for lowered vehicles, these headers provide maximum ground clearance to prevent scraping while maintaining optimal exhaust flow.
