Arvinode Dual Exhaust System - Arvinode Is Back
Now There's An Authentic Reproduction For The Rare Dual Exhaust System Found On Many 289 High Performance Mustangs
Karl Seifert in the Hi-Po Forum introduced Dave to "Herschel-Quincke," a sound attenuation principal used for noise control. Figuring the technology was patented, Dave contacted the U.S. Patent Office for Herschel-Quincke information. It turns out there were numerous patents for this unique sound science based on "node" dampening, a number of them registered by Arvin during the 1960s. Dave noted the names of company engineers associated with the patents. He tracked down two of them, Benjamin Irwin and Ed Ludlow, in Columbus, Indiana, where Arvin Industries was located. Unfortunately, both had passed away. However, Ben Irwin's son, Dick, put Dave in touch with Jim Abbott, the former prototype shop foreman at Arvin. Jim, who had fabricated the prototype and production patterns, was able to find the original drawings for the mufflers and resonators.
Across the miles, everyone pooled resources, making it possible for Waldron's Antique Exhaust to reproduce the Arvinode dual exhaust system with painstaking accuracy. The objective was to produce a system that would pass the scrutiny of the toughest Mustang Club of America '65-'66 judges. As luck would have it, Dave heard from former Ford engineer Tom Glotkowski who had the original Ford engineering drawings for the exhaust pipes. He sent them to Waldron's, which went to work producing accurate reproductions.
The reproduction Arvinode exhaust is perfect for '65 Hi-Po Mustangs built between October 15, 1964, and March 1965, but it also fits any '65-'66 Mustang with a 289 engine. In addition to the concours style that is visually correct, Waldron's also offers the system as a non-concours version for those who want the sound but are not concerned with a factory-original appearance. Both versions are available through National Parts Depot.
