JBA 87-91 Chevrolet Blazer 5.0L/5.7L w/o A.I.R. 1-5/8in Primary Raw 409SS Cat4Ward Header

When you're looking to get more out of your engine, a set of JBA Cat4Ward headers is a solid choice. This particular set is built for 1987-1991 Chevrolet Blazers and GMC Jimmys with 5.0L or 5.7L engines, specifically those without A.I.R. injection. These headers replace your restrictive factory exhaust manifolds, helping your engine breathe easier and making a noticeable difference in power and efficiency.

JBA builds these headers from durable 409 stainless steel tubing, which holds up well to the demands of daily driving, towing, or even some spirited runs. The flanges are a beefy 3/8-inch thick with oversized exhaust ports to match the tubing, and they feature JBA's proprietary Firecone collector design. This design is focused on maximizing torque and power gains in the RPM range you'll use most often. You also get factory-style emission connections, and JBA includes high-quality hardware to help ensure a professional, leak-free installation right out of the box.

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. They come with everything you need for installation, so you can get them bolted up and start enjoying the improved performance.
