Banks Monster exhaust includes a stainless steel, low-restriction Dynaflow
muffler that is acoustic tuned to release a pleasing rumble. The Dynaflow
features a four-inch outlet that mates to four-inch exhaust pipes, which
vary according to application. Built of heavy-duty stainless steel, these
mandrel-bent pipes maintain the same diameter through every turn and never
crack or blow. Finishing the serious power look is a colossal five-inch,
polished-stainless tailpipe tip.
