Each BBK Full-length header system is CAD designed and manufactured with 1 5/8" CNC mandrel bent tubing for unrestricted airflow and a one-piece 3/8” laser cut flange for added strength and durability. Featuring a bright chrome finish these headers will sit nicely in any 99-04 Cobra or Mach 1. 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 in Southern California for maximum performance. Results have shown an additional 15-20 rear wheel horsepower over-stock. BBK’s Mustang full-length headers are recommended for built engines and high-performance applications. They offer BBK’s distinctive quality that guarantees many years of top performance.
BBK full-length headers require a BBK short X pipe or H pipe to complete installation to the cat-back exhaust system.
