BBR D3 EXHAUST SYSTEM BBR's new D3 exhaust is the latest generation in BBR's legendary D-Section exhaust systems. This design incorporates an air-craft quality stainless steel header that has been tuned specifically to optimize performance and power gains. An all new, lightweight "D" profile muffler is used to drastically reduce weight on all models. BBR's unique "D" muffler allows maximum tire clearance and packing volume. A lightweight carbon fiber endcap incorporates a chrome "D3" emblem. The head shield is also carbon fiber and includes drilled "Works Type" washers. For all applications, the new BBR D3 comes as complete systems, including a header and muffler. A USDA Forest Service approved spark arrester is included. If you need to reduce the dB level, BBR offers an optional Cancel Core Insert, that will keep the neighbors happy. Every BBR D3 exhaust includes a rubber end plug, for use when washing your bike, as well as a spring puller to ease installation. We've thrown in a bunch of decals and heat shield tape and put these accessories in a BBR black canvas zipper case.
