For over 50 years, PACEMAKER has been renowned for its innovative exhaust headers crafted in Australia. The brand was the first to introduce mandrel-bending technology to the header market, revolutionizing the industry. PACEMAKER continues to push the bar, utilizing advanced technology to develop one of Australia's largest Tri-y and 4-into-1 catalogs. In 1997, PACEMAKER launched its Pipe Over Cone™ technology (copyrighted design number 135712) to reduce turbulence and extend the product's life.

Pacemaker stocks quality headers featuring their "Mandrel Bend" System. Their cutting edge facility equips a computer-controlled Bender with a patented vertebrate-type mandrel, creating round bends previously inaccessible in Australia. Moreover, Pacemaker's headers come with precision laser-cut, machined flanges, jig-welded joints, hi-tensile bolts, big bore pipes, and emission hook-ups. For added protection, these headers are finished with a heat-proof finish tested up to 1270°, and feature Pipe Over Cone™ technology (copyright number 135712). This special technology increases exhaust gas flow, reducing turbulence within the header and resulting in improved power and performance. |
