The H8012-B GM Headers are made of premium 304 stainless steel, ensuring durability and resistance to corrosion. Each header comes with two collectors, perfectly suited for use with 1.5 or 1.65-inch primary exhaust systems.

The headers are also designed to work seamlessly with your vehicle's factory catalytic converters, making them a great choice for those looking to maintain their emissions compliance while still enjoying the performance benefits of headers.

Installation of the H8012-B GM Headers is made easy with the included stud kit and gaskets. The headers come with a comprehensive installation guide, ensuring that the process is as straightforward as possible.
