JBA 88-95& 02-03 GM S-Truck 4.3L V6 2WD 1-1/2in Primary Raw 409SS Cat4Ward Header

Starting with 3/8" thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle the demands of your GM S-Truck. They're designed to significantly reduce restriction compared to the factory exhaust manifolds, which can lead to improved engine power and efficiency. This makes them a notable performance upgrade for your 4.3L V6 engine, whether you're using your truck for daily driving, towing, or even some spirited off-road adventures.

Constructed from durable 409 stainless steel, these headers are made to last. The tubing is mandrel bent for smooth airflow, and JBA's proprietary Firecone collector design uses race-proven technology to maximize power and torque gains in the RPM range you'll use most often. The extra thick collector domes add to the overall robustness of the header. These headers also include factory-style emission connections, ensuring you can maintain emissions compliance, and come with high-quality hardware to help ensure a professional, no-leak installation.

This header fits a range of GM S-Truck models, including Chevrolet S10, Chevrolet Blazer, GMC Sonoma, and GMC S15 Jimmy from various years. It's a solid option for anyone looking to get more out of their 4.3L V6 engine.
