Uniquely constructed of an aerospace quality ultra-light weight stainless steel in a FOUR into TWO into ONE configuration for a smooth torque curve with a megaphone induced peak power punch! A removable 2 1/4 outlet Billet Aluminum/stainless steel/fiberglass constructed baffle is included. As usual, the Brock's oversize tube design (Tapered 1 3/4" primaries meet DUAL 2" secondary pipes which merge into a velocity enhanced 2 1/4" collector) complements the ram air efficiency of the Hayabusa. This is the preferred exhaust for "MYRTLE WEST" phatty tire kits because your stock exhaust will not clear the tire!
