JBA 87-91 Chevrolet Blazer 5.0L/5.7L w/o A.I.R. 1-5/8in Primary Silver Ctd Cat4Ward Header

When you're looking to get more out of your 1987-1991 Chevrolet Blazer or GMC Jimmy with a 5.0L or 5.7L engine, these JBA Cat4Ward headers are a solid option. What you get in this package are the headers themselves, constructed from durable stainless steel, featuring JBA's proprietary Firecone collector design. You'll also find factory-style emission connections and all the necessary high-quality hardware to ensure a professional, no-leak installation right out of the box.

These headers are designed to be significantly less restrictive than your stock exhaust manifolds. The 1-5/8 inch primary tubes are mandrel-bent for smooth airflow, and the 3/8 inch thick machined flanges have oversized exhaust ports to help maximize power and torque gains, especially in the RPM range where you do most of your driving. The extra thick collector domes add to the overall robustness of the system. This well-built stainless steel construction is meant to handle the demands of daily driving, towing, or even some spirited use.

This header set is designed to fit a range of GM trucks and SUVs from the late 80s and early 90s, including models like the Chevrolet R10 and GMC V1500 Suburban. It's a direct replacement for your factory manifolds, making installation more straightforward. Remember to consult the manufacturer's installation instructions for any specific details regarding your vehicle.
