In the performance automotive realm, few components generate as much debate as downpipes. More specifically, the discussions center on whether to opt for catted or catless variants. However, before delving into the differences, pros, and cons of each, it's essential to understand what downpipes are and how they function in your vehicle.

Downpipes are a critical part of your car's exhaust system, linking the turbocharger to the rest of the exhaust. Their primary purpose is to direct the exhaust gases away from the engine, but different downpipe types can influence the vehicle's performance and sound differently.

Catted Downpipes

Catted downpipes, as the name implies, contain a catalytic converter. The primary role of the catalytic converter is to decrease harmful emissions produced by the engine's combustion process. This component uses a combination of heat and metals as catalysts to trigger chemical reactions converting harmful gases into less damaging substances before they exit the tailpipe.

The major advantage of catted downpipes is their ability to reduce harmful emissions, making them a more environmentally friendly choice. Moreover, because they help you stay within emission standards, they often pass the emission tests in most regions. However, it's crucial to check which cats are used in the downpipe for a better understanding of whether it will trigger the check engine light, as some high-performance catted downpipes might still do so.

Additionally, catted downpipes generally produce a more refined, deeper mid-range tone, which many car enthusiasts find appealing.

Catless Downpipes

On the other hand, catless downpipes, often referred to as "straight pipes," exclude the catalytic converter. As a result, the exhaust gases flow freely without any restrictions, potentially offering a slight edge in performance due to decreased backpressure.

However, catless downpipes come with their own set of drawbacks. They often fail to meet emission standards, which might cause issues with passing emission tests, and are consequently not sold at Extreme Power House. Furthermore, they tend to release a more pungent exhaust smell, as the gases aren't being converted to less harmful substances, which can be a deterrent for many drivers.

In terms of sound, catless downpipes are louder than their catted counterparts but often result in a raspier exhaust note. This characteristic can be a pro or con depending on personal preferences.

Conclusion

When deciding between catted and catless downpipes, it ultimately comes down to your individual needs, preferences, and local laws. It's critical to do your due diligence before making a decision. While Extreme Power House does not offer catless downpipes, we have a wide range of high-quality catted downpipes .
