In this article, we’ll explain what a catback exhaust system is, what it does, and why it’s different from your run-of-the-mill exhaust systems. There are seemingly endless available upgrades when looking to enhance vehicle performance. It certainly rings true when it comes to your vehicle’s exhaust system. One term that you’ve probably heard if you’re in the market for an aftermarket exhaust upgrades is cat-back exhaust. What exactly does it mean, and how does it change the way your vehicle performs? This 2009 Pontiac G8 GXP is one of approximately 1,830 examples produced, and it has 16k miles.
In California, it is illegal to select a catalytic converter for installation based solely on vehicle weight and engine size. The design of these systems often sees an increase in horsepower compared to the factory design of a vehicle. Because stock models try to minimise materials and maximise space, with horsepower as a lower priority.
Finally, the catalytic converter can become fouled over time, resulting in a loss of power. This can be remedied by having the converter cleaned or replaced as needed. When it comes to choosing the right cat back for your car, there are a few things you need to keep in mind. First, you need to make sure that the cat back you choose is compatible with your car's make and model. Are you an aggressive driver who likes to take corners at high speeds?
Engines fitted with regulated 3-way catalytic converters are equipped with a computerized closed-loop feedback fuel injection system using one or more oxygen sensors (also known as Lambda Sonds or sensors). Other variants combined three-way converters with carburetors equipped with feedback mixture control were used. An unregulated three-way converter features the same chemical processes but without the oxygen sensor, which meant higher NOx emissions, particularly under partial loads. These were low-cost solutions, typically used for retrofitting to older cars or for smaller, cheaper cars. Axle-back exhaust systems replace only your vehicle’s rear exhaust section, usually consisting of items behind the rear axles, like rear exhaust pipes, muffler, and exhaust tips. A
