What material are these JBA headers made from?

These JBA headers are constructed from durable stainless steel tubing. The flanges are 3/8-inch thick machined steel, and the collector domes are extra thick for added longevity.

Do these headers come with all the necessary hardware for installation?

Yes, these headers include high-quality hardware to assist with a professional, no-leak installation. They also feature factory-style emission connections.

What is the benefit of the JBA Firecone collector design?

The proprietary JBA Firecone collector design uses race-proven technology. It is engineered to produce maximum power and torque gains in the lower to mid-range RPMs, which is where most daily driving occurs.

Product Details

The 3/8-inch thick machined flanges on these JBA headers are a solid starting point, ensuring a flat, leak-free seal against the cylinder head. These headers are built for the 2004-2006 Pontiac GTO with the 5.7L or 6.0L LS engine. They replace the restrictive stock exhaust manifolds with a less restrictive design, which can significantly increase engine power and efficiency. The primary tubes are 1-5/8 inches in diameter, designed to improve exhaust flow and torque gains in the RPM range where you do most of your driving.

Constructed from durable stainless steel, these headers are made to handle the demands of daily driving, towing, or even racing. JBA's proprietary Firecone collector design is a key feature, using proven race technology to maximize power and torque. The tubing is mandrel bent, which means it maintains its diameter throughout the bend, allowing for smoother exhaust gas flow compared to crush-bent tubing. The collector domes are extra thick for added durability.

Installation is made easier with the inclusion of factory-style emission connections, so you can retain your emissions equipment. High-quality hardware is also included to help ensure a professional, no-leak installation. These headers are a well-built upgrade for your GTO's exhaust system.
