BBK 1979-1993 Mustang 351W Swap Headers
These High-Performance BBK 351 swap Full-length headers have been designed specifically for any Mustang enthusiast who wishes to swap out the smaller 302 blocks for a larger/ taller 351 block engine. For nearly 20 years Mustang enthusiasts have made BBK CNC-Series full-length headers the number one choice for their Fox body Performance Mustangs.
Each BBK long tube 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 exhaust 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.
BBK long tube headers require one of the following BBK X-pipe or H-pipe to complete installation.
- Fits 1979-1993 Mustang w/ 351 swap and manual transmission (May hit bell housing)
