Matte black ceramic coated finish. With PCX™ high flow catalyst technology. Exhaust system with black CNC machined end caps. Where the 2-2 Grenades are awesome; the Mini Grenades show that minimalistic design principles can be driven even further. An instant brute; basic and powerful visual message with an aggressive and deep sound to match. A statement no one can overlook. Complete with a 4" 3-step muffler body; 2-1/4" heat shields and 1-3/4" header pipes. Compatible with both mid and forward control models. Comes with PCX™ (Power Chamber Exhaust) technology; which integrates chambered high-flow catalysts for a tuned growl and greater boost in torque as you accelerate through the gears. - PCX™ (Power Chamber Exhaust) technology - Chambered high-flow catalyst cartridge designed to Increase torque - Full coverage heat shields Vance & Hines innovative PCX™ Technology explained: More Power & Less Heat. The PCX™ (Power Chamber Exhaust) Technology are factually chambered high-flow catalysts. Used to increase mid-range torque for more responsive acceleration off the line. They are positioned downstream for up to 20% less heat at the floorboards / foot pegs and 50% less heat at the collector; to optimize rider comfort over the stock system. PCX™ technology uses a high-flow double-matrix catalyst that improves torque delivery through the mid-range for more responsive acceleration. All while producing an even deeper full-throated rumble; all with no compromise to the styling o
