High-Performance Shorty Tuned Length Headers 1-3/4 Mandrel-Bent Tubing Steel Construction With Silver Ceramic Polished Finish 16-Guage Tubing 3/8 Flange Thickness CAD Designed 3 Collector Diameter Includes: Gaskets, Hardware, & Installation Instructions Firebird LS1 BBK shorty tuned exhaust headers are an easy way to increase the horsepower in your 1998 or 1999 Firebird. Whereas stock manifolds combine exhaust gases from each exhaust port on the cylinder head as soon as the gases leave the engine, headers provide a single exhaust tube for each port, resulting in an easier workload when your engine evacuates the gases. These exhaust headers are designed for direct bolt-on performance to the existing stock exhaust system. Each BBK exhaust header system are CAD designed and are manufactured with 1- 3/4 CNC mandrel bent tubing for unrestrictive airflow and a one piece laser cut flange 3/8 for added strength and durability. When you are in the market for performance at a value, invest in shorty tuned exhaust headers for your 1998 and 1999 Firebird LS1.
