BD Diesel Electronic Exhaust Brake 4in - 2007.5-2017 Ram 2500/3500 6.7L Cummins

The 6.7L Cummins pulls hard, and it pushes just as hard when you're coming down a grade with a trailer behind you. BD's electronic exhaust brake mounts in-line in the 4in exhaust and builds controlled backpressure so the engine does more of the slowing.

It's electrically actuated, so there's no compressor or air plumbing to find room for, and it ties into the factory exhaust brake button you already have on the dash.

Why we like it

• BD Variable Orifice Technology regulates backpressure across the RPM range
• Up to 150 retarding horsepower (BD rating)
• Electric actuation - no compressor, tank or air lines
• Works with the factory dash exhaust brake button
• 4in in-line valve
• Backed by BD's 24-month / 24,000-mile warranty
