This Chambermaid system is a tunable 2-2 system that is sits flush at the muffler ends. Oversized headers with welded on heat shields keep your blues at bay and your heat shields solidly intact. Removable 1 3/4" baffles offer just the right amount of back pressure for optimum performance and sound. Our 'Torque Chamber' inserts are included and are designed to replace the baffle and offer a much more aggressive sound while still maintaining proper back pressure and extracting every ounce of power from your motorcycle giving you the option to tune the system to your riding style. Chrome end caps also come standard with this system
