What is the difference between catless downpipes and catted downpipes?
When it comes to modifying a high-performance car's exhaust system, one of the most popular upgrades is replacing the factory original catalytic converters with aftermarket ones. The two main options available are catless downpipes and catted downpipes (downpipes with Hight Flow Sports Catalytic Converters). Both options have their pros and cons, and the best choice ultimately depends on your specific needs and goals.
Catless Downpipes:
Catless downpipes, as the name implies, do not have catalytic converters installed. The absence of a catalytic converter allows for better exhaust flow, resulting in increased horsepower and torque. This also leads to a more aggressive exhaust note, which many car enthusiasts find appealing.
However, there are some downsides to choosing catless downpipes. Without a catalytic converter, the exhaust gases emitted by the engine contain more harmful pollutants, which can negatively impact the environment. Additionally, in some areas, the use of catless downpipes is not street legal, and driving with them can result in fines or penalties.
Catted Downpipes (downpipes with Higt Flow Sports Catalytic Converters):
Catted downpipes come equipped with a Hight Flow Sports Catalytic Converter, which helps to reduce the level of harmful pollutants in the exhaust gases. A sports catalytic converter is less restrictive than a factory one, allowing for improved exhaust flow and increased performance. Downpipes with sports catalytic converters are designed to strike a balance between improved performance and reducing harmful emissions. Catted downpipes help to reduce the level of pollutants in the exhaust gases. This reduction in pollutants often results in a less potent or even odourless exhaust smell.
Another significant difference between catless and catted downpipes is their exhaust sound. Catless downpipes typically result in a louder and more aggressive exhaust note. This is because the absence of a catalytic converter allows for freer exhaust flow, resulting in a deeper and more resonant exhaust sound.
Downpipes with sports catalytic converters are often designed to maintain some of the exhaust sound improvement benefits while also reducing the amount of noise produced. The result is a more refined exhaust note that is still louder and more aggressive than the stock exhaust system but without the drone and harshness that can sometimes come with catless downpipes.
Which is Better?
Deciding which option is better depends on your priorities.
While catless downpipes may result in a more aggressive exhaust note, they may also emit a stronger smell and produce more pollutants. Catted downpipes, on the other hand, offer a more refined exhaust note while still improving performance and reducing emissions.
Ultimately, the decision on whether to choose catless downpipes or catted downpipes with sports catalytic converters comes down to personal preference, budget, driving habits, and local regulations.
