A cat-back exhaust system is an aftermarket exhaust system that replaces the components of the exhaust system from the catalytic converter to the exhaust tips. The term "cat-back" stands for "catalytic converter back."A cat-back exhaust system typically includes the following components:
These are the sections of the exhaust system that connect the catalytic converter or resonator to the muffler.
The cat-back system may include one or multiple mufflers, which help reduce exhaust noise and improve exhaust flow.
These are the sections of the exhaust system that extend from the muffler to the exhaust tips, providing the exit path for the exhaust gases.
The main purpose of a cat-back exhaust system is to improve the performance and sound characteristics of a vehicle. A cat-back system can offer benefits such as:
Increased Exhaust Flow
Aftermarket cat-back systems are often designed with larger-diameter pipes and less restrictive mufflers, allowing for better exhaust gas flow. This can potentially lead to improved engine performance by reducing backpressure.
Cat-back exhaust systems can provide a more aggressive and sporty exhaust note compared to the stock exhaust.
Cat-back systems often come with larger or differently styled exhaust tips, which can enhance the visual appearance of the vehicle's rear end.
