Description
Excellent Headers. These JBA 1-1/2-Inch Shorty Headers with a Natural finish are the perfect upgrades for your 4.3L Sierra 1500. Their less restrictive design gives them a better flow, as well as a sturdier construction than your stock headers. This way, your truck will get better torque and horsepower gains, as well as improved engine performance.
Enhances the Vehicle's Road Presence. Not only will these headers give your truck a significant performance boost, but they'll also give it a more aggressive road presence. Their high-quality design and construction allow them to generate a louder exhaust sound, so your vehicle will steal the show every time you head out.
Mounts to OE Catalytic Converters. You don't need to purchase new catalytic converters to ensure that these headers fit your truck. They're designed with factory-style emission connections, so they work seamlessly with your vehicle's current setup.
Highly Durable Upgrade. Constructed from 16-gauge, mandrel-bent, 409 stainless steel, these headers offer a sturdier and longer-lasting performance. Their high-quality build ensures that they can handle the heat of your truck's engine, as well as the demands of your high-performance drives. Moreover, they come complete with a natural finish for added durability.
Further Tuning Isn't Needed. JBA designed these headers to operate with your vehicle without having you make any complicated modifications. As a result, tuning isn't needed during the installation.
CARB-Regulated Headers. These shorty headers comply with the standards set by the CARB. Their CARB EO number is D-57-33.
