Designed to replace the factory exhaust system from the catalytic converter rearward, these cat back exhausts offer a deeper, more aggressive exhaust note while reducing restriction for improved airflow.

This is achieved by burning off the excess hydrocarbons which result from the extra-rich mixture required for a cold start. Slightly lean of stoichiometric, the exhaust gases from the engine contain excess oxygen, the production of NOx by the engine increases, and the efficiency of the catalyst at reducing NOx falls off rapidly. However, the conversion of HC and CO is very efficient due to the available oxygen, oxidizing to H2O and CO2. However, the efficiency of the catalyst at reducing NOx is good, and the production of NOx by the engine decreases.

Exhaust systems also play a role in reducing noise levels, improving engine performance and reducing fuel consumption. To get the power level up to 785 hp, Shelby installs a Ford Performance supercharger, as well as a new carbon-fiber air intake tube, high-performance fuel injectors, and an aluminum heat exchanger. A Borla (cat-back) exhaust system rounds out the list of powertrain modifications.

The first widespread introduction of catalytic converters was in the United States automobile market. The exhaust system is crucial to a car’s performance, especially the catalytic converter which can go bad if it’s overworked. A stock exhaust system strives to minimize the car’s materials while maximizing space. This means that the exhaust system’s performance can suffer, having to work harder with less horsepower.

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.

The difference is that the dual exhaust system has two exhaust systems on one vehicle. Meaning, when modifying your exhaust, never start from the front of your turbocharged vehicle with a downpipe or with headers on your naturally-aspirated platform, you will create a bottleneck in the flow. By starting with a cat-back first, your exhaust gases will flow more freely if the rest of your system is stock.
