A 4-inch exhaust adapter is needed to install the BD Diesel Performance Remote Mount Vacuum Exhaust Brake on our ’99 Dodge Ram 3500’s 3.5-inch custom exhaust.

After our ZZ632 swap our Project X 1957 Chevy needed an exhaust system. With no off-the-shelf systems available we turned to Summit Racing and their universal kit.

These universal exhaust pipe packages are available in 2.25-, 2.5-, and 3-inch diameters, and come with all the pipes needed to build a dual exhaust for most any fullsize '50s or '60s car.
