The Hummer H2 is one tough truck and Hummer owners expect nothing less from aftermarket Hummer components. MagnaFlow's H2 performance exhaust system meets the "Tough" criteria with every component made from the highest quality stainless steel. The exhaust system delivers performance and style, featuring 3" fast-flowing mandrel-bent inlet pipes, a 22" long, 5" x 11" MagnaFlow Performance Muffler with built-in Tru-X Core. From there, the exhaust flows through dual tail pipes and custom dual polished stainless steel rear exit exhaust tips. Magnaflow exhaust systems have the highest exhaust flow rates and deliver the greatest quality of any Performance Exhaust System.
