JBA 14-20 GM Truck 4.3L V6 1-5/8in Primary Ti Ctd Cat4Ward Header

If you're looking to get more out of your 2014-2020 Chevrolet Silverado 1500, especially with the 4.3L V6 engine, upgrading the exhaust manifolds to headers is a smart move. Stock manifolds can really choke up an engine, limiting how much air and fuel can get in and out. These JBA Cat4Ward® shorty headers are built to replace those restrictive factory parts, helping your engine breathe better and make more power, particularly in the RPM range you use most often for daily driving and towing.

JBA constructs these headers from strong stainless steel tubing, which is much more durable than the cast iron manifolds they replace. They feature a 3/8-inch thick machined flange for a solid seal against the cylinder head, and the ports are oversized to match the engine's flow needs. A notable feature is JBA's proprietary Firecone collector design, which they say uses race-proven technology to maximize torque and power gains where you need them. They also include factory-style emission connections, so you can hook up your O2 sensors and keep your check engine light off, and they come with high-quality hardware for a clean, no-leak installation.

These headers are designed as a direct fit for your Silverado 1500 or GMC Sierra 1500, making installation more straightforward than some other header designs. You'll want to refer to the manufacturer's installation instructions for specific details on mounting and any other components you might need to complete the job, but they are designed to work with your existing exhaust system.
