Cat Back or Turbo Back Exhaust System… Which is right for your diesel truck?

Intake Exhaust Diagram

At, we sell all types of exhaust systems. But which is the right one for you? It all depends on how you use your diesel truck. The two most common types of exhaust systems would be Cat Back and Turbo Back.

Cat Back refers to the portion of the exhaust system from the outlet of the catalytic converter to the final vent to open air. Cat Back systems generally include the pipe from the converter to the muffler, the muffler, and the final length of pipe to open air. Cat Back exhaust systems are a very popular aftermarket performance enhancement. They generally use larger diameter pipe than the stock system. Good systems will have mandrel-bent turns that allow the exhaust gas to exit with as little back pressure as possible.

Turbo Back refers to the part of the exhaust system from the outlet of a turbocharger to the final vent to open air. Turbo Back systems are generally produced as aftermarket performance systems for cars with turbochargers. Some Turbo Back systems replace stock catalytic converters with others having less flow restriction.
