JBA 03-13 GM Truck 4.3L V6 1-1/2in Primary Ti Ctd Cat4Ward Header

When you're looking to get more out of your 2003-2013 Chevrolet Silverado 1500 or GMC Sierra 1500 with the 4.3L V6 engine, this JBA Cat4Ward header set is what you'll find in the box. You get the headers themselves, which are built from strong stainless steel tubing, along with a proprietary Firecone collector design. The package also includes factory-style emission connections and all the necessary high-quality hardware for a professional installation that won't leak.

These headers are a significant upgrade over the stock exhaust manifolds. The 1-1/2 inch primary tubes and oversized exhaust ports, combined with the mandrel-bent tubing, create a much less restrictive path for your exhaust gases. This improved flow helps your engine breathe better, which can lead to noticeable gains in power and torque, especially in the RPM range where you do most of your driving. The 3/8 inch thick machined flanges are extra thick at the collector domes, ensuring a solid seal and durability for daily driving, towing, or even track use.

Installing these headers is a great way to wake up the performance of your truck. They're designed to fit right onto your specific GM truck, and the included hardware and emission connections make the job straightforward for someone familiar with exhaust work. You'll notice a deeper exhaust tone and a more responsive feel from your engine after installation.
