The BD Diesel exhaust brake for 2004.5–2010 Duramax 6.6L (stock exhaust) is a variable regulating back‑pressure brake that mounts either in place of the factory turbo elbow or inline in the exhaust. Its rugged cast‑iron housing uses BD's AlumiBronze bushing and sealed piston ring; the design employs Variable Orifice Technology and a stainless steel butterfly shaft to deliver smooth retarding across the engine's RPM range. Kits include hardware and control components.
