In 2010, most light-duty diesel manufacturers in the U.S. added catalytic systems to their vehicles to meet federal emissions requirements. Two techniques have been developed for the catalytic reduction of NOx emissions under lean exhaust conditions, selective catalytic reduction (SCR) and the NOx adsorber. Unleash your truck’s hidden potential by installing less restrictive exhaust components.

They directly bolt on to where the original exhaust sits and do not require any further modification. Cat back exhaust systems come with exhaust pipes, muffler and exhaust tips, so you have everything you need to replace the exhaust. The cat back is the section of the exhaust that runs from the outlet of the catalytic converter to the exhaust tips. Exhaust systems that include this often feature a large pipe running from the converter to the muffler, with mandrel-bent turns and glasspacks for reduced back pressure. Your go-to spot for information on the exhaust system, as well as mufflers, catalytic converters, pipes and sensors.
By running pipes from the catalytic converter to the muffler and from the muffler to the exhaust tip, cat back exhaust systems improve exhaust gas flow, providing small performance boosts. However, your performance gains may be limited if your catalytic converter restricts gas flow, as a catback exhaust system is installed ‘downstream’ of the converter. Header-back systems are increasingly rare, namely because of modern emissions systems. Since removing your vehicle’s factory emissions components is highly illegal, the previous two options are more common. However, header-back systems are still available for some older, pre-emissions applications. In these cases, header-back systems offer more performance and volume than cat-back or axle-back systems
