Ultimate Headers continues to break new ground in the exhaust header market, with a focus upon joining form and function to address several key areas of concern. Utilizing stringent engineering best practices, leading edge computer-aided design and manufacturing, and aircraft-grade materials, these headers take on a whole new perspective in terms of appearance, design and functionality.

Ultimate Headers incorporates patented engineered investment cast flanges, and investment cast elbows with tight radius bends so you can have “BIG TUBES for TIGHT PLACES”. The 1-7/8″ diameter provides more power for 600+ horsepower motors.

Premium grade 321 Stainless Steel delivers an additional margin of superior durability over other stainless steel options. 321 Stainless Steel is 50% stronger at operating temperatures over 304 Stainless Steel, making for a more robust, ultimate performance header.
