Hummer H3 MagnaFlow Catalytic Converters 

Hummer H3 Magnaflow catalytic converters are OEM quality because, in many cases, Magnaflow is the original manufacturer for many vehicle makers. As the brand's name implies, Hummer H3 Magnaflow catalytic converters provide maximum exhaust flow while filtering out and converting harmful emissions that would otherwise enter our atmosphere.
