More on Downpipe Back Exhaust Systems from OC Diesel

In certain downpipe back exhaust systems, a catalytic converter with more flow than the original converter is included. In others, the catalytic converter is removed completely and replaced with just a pipe. Removing it will generally give an increase in horsepower, but is not legal in most states because it is considered the removal of an emissions control device.
