JBA 99-02 GM Truck 4.3L V6 w/o A.I.R. Injection 1-1/2in Primary Raw 409SS Cat4Ward Header

If you're looking to get more out of your 1999-2002 Chevrolet Silverado 1500 with the 4.3L V6 engine, these JBA Cat4Ward headers are a solid option. They replace the restrictive factory exhaust manifolds with a less restrictive design, which can help your engine breathe better. This improved airflow often translates to increased power and better efficiency, making your truck feel more responsive, especially in the lower and mid-range RPMs where you do most of your driving.

These headers are built from 409 stainless steel, a well-built material that holds up well against the heat and potential corrosion from daily driving and towing. The primary tubes are 1-1/2 inches in diameter, and they feature JBA's proprietary Firecone collector design. This design is focused on maximizing torque gains in the RPM range you'll use most often. The flanges are a stout 3/8 inch thick with oversized exhaust ports, and the collector domes are extra thick for durability. They also include factory-style emission connections, so you can retain your emissions equipment for a cleaner exhaust, and come with the necessary hardware for a no-leak installation.
