JBA 96-01 GM S 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 1996-2001 Chevrolet Blazer, S10, GMC Jimmy, or Sonoma with the 4.3L V6 engine (without A.I.R. injection), these JBA Cat4Ward headers are a solid option. They replace your restrictive factory exhaust manifolds with tubes that flow much better, helping your engine breathe easier. This can lead to improved power and better efficiency, especially in the RPM range where you do most of your driving.

These headers are built from 409 stainless steel, which is known for its durability and resistance to corrosion, making them a well-built choice for daily driving, towing, or even some spirited use. The primary tubes are 1-1/2 inches in diameter, and they feature JBA's proprietary Firecone collector design, which is engineered to maximize power and torque gains. The flanges are a stout 3/8 inch thick with oversized exhaust ports, and the whole assembly is constructed with mandrel-bent tubing for smooth airflow. They also include factory-style emission connections and high-quality hardware to help ensure a leak-free installation.
