Product Details

When you're looking to get more out of your 2004-2006 Pontiac GTO's 5.7L or 6.0L LS engine, these JBA Cat4Ward headers are a solid choice. They replace the restrictive factory exhaust manifolds with a less restrictive design, which can help your engine breathe better. This improved airflow often translates to noticeable gains in power and overall efficiency, making your GTO feel more responsive.

JBA builds these headers from durable 409 stainless steel, which holds up well to the heat and stress of daily driving, towing, or even track use. The primary tubes are 1-5/8 inches in diameter, and they feature JBA's proprietary Firecone collector design. This collector is engineered to maximize power gains in the RPM range you'll use most often. The flanges are a beefy 3/8 inch thick with oversized exhaust ports, and the collector domes are extra thick for added durability. You also get factory-style emission connections, and JBA includes the necessary hardware for a professional, no-leak installation.

This kit comes with the headers themselves, factory-style emission connections, and high-quality installation hardware. It's designed to be a direct fit for your 2004-2006 Pontiac GTO, making the installation process as straightforward as possible. If you're aiming for improved performance and a more aggressive engine note, these JBA headers are a well-built option.
