These Performance BBK 351 swap Full-length headers have been designed specifically for any Mustang enthusiast who wishes to swap out their smaller 302/5.0L engine for a larger/taller 351/5.8L engine. For 20+ years Mustang enthusiasts have made BBK CNC-Series full-length headers the number one choice for their Fox-body Performance Mustangs.
Each BBK Longtube Header Exhaust Kit is CAD designed and manufactured with 1 3/4" CNC mandrel bent tubing for nonrestrictive airflow and a one piece 3/8" laser cut flange for added strength and durability. ALL BBK Mustang headers are pressure tested to ensure leak-free performance. Each BBK full-length exhaust header system has been designed and dyno-tested at the BBK headquarters for maximum performance. Results have shown an additional 18-25 rear wheel horsepower over stock. All exhaust header kits include new gaskets and hardware.
