Unleash the American Muscle V8 Special Edition Prism Proton Pyro! The Pyro Special Edition has a triple-foil stamp by MVP Art Director Mike Inscho which captures the raw energy and power of a wide-open engine. The Prism Proton Pyro can handle full power and that is represented in the redlining engine stamp! This Special Edition celebrates Axiom’s first Overstable Midrange, having a special combination of SE stamp along with the gorgeous Proton core and Prism rim.
