All aFe exhaust systems are engineered and manufactured in our Corona, California facility. The price of a cat back exhaust system can vary widely depending on the make and model of your vehicle, the materials used, and the complexity of the design.

One issue is that the system can become clogged with dust and debris over time, causing reduced performance. This can be remedied by regularly cleaning the system with compressed air or a soft brush. Finally, it's always a good idea to check for leaks after installation.

Beyond these incremental advantages, there’s not much to tell cat-back and regular exhausts apart, as they are commonly made from the same types of materials in roughly the same shape. Most newer vehicles have electronic fuel injection systems, and do not require air injection systems in their exhausts. Instead, they provide a precisely controlled air-fuel mixture that quickly and continually cycles between lean and rich combustion. Depending on your make and model, cat back exhaust systems can lead to an increase in fuel economy. The engine doesn’t have to work as hard pushing exhaust gases through the piping which reduces its load and leads to higher efficiency and MPG. For car enthusiasts and performance drivers, upgrading the exhaust system of a vehicle is a no-brainer.

Each cat-back exhaust system is made from high quality components and assembly so you can get the performance you want at a price you can afford with the assurance you need.

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.
