Power and emission control with catted down pipes
Upgrading your exhaust system is essential to get the most out of your vehicle, and catted downpipes allow you to get performance boosts without sacrificing emission control. Catted options from Invidia include catalytic converter technology, which effectively filters your emissions so that up to 90 per cent of harmful fumes and toxic pollutants are not released into the atmosphere.
These solutions come with high-flow catalytic converters that include noble metals like platinum, palladium, and rhodium. These metals then have a chemical reaction with the gases that pass through them, converting unburned fuel into either oxygen, carbon dioxide or harmless nitrogen.
It means you can have most of the power that you can achieve through a catless downpipe, without the harmful emissions that come with them.
When do I need aftermarket down pipes?
For those that are just starting in their car enthusiast journey, the exhaust system is the best place to start for your aftermarket improvements.
Down pipes are required when you have a turbocharger as they have been specifically engineered to allow proper airflow and prevent pressure building up, which can damage your turbo and engine.
Stock pipes are much too thin, and their catalytic converters are also restrictive, limiting the power your turbo can generate. Catted alternatives allow you to retain your emission control, while still allowing your gases to flow correctly and generate the extra power you need.
Are catted less efficient than catless solutions?
In some cases, you may notice a slight performance hit. This is usually in the range of 5-10HP and depends on the type of vehicle you are driving, the turbocharger, tuning, quality of down pipes and your system. The choice ultimately comes down to whether that 5-10HP is essential at the expense of controlling the gasses released, which can be harmful to people and the environment.
A catted solution is still going to deliver a boost of around 40HP in most instances compared to stock options, so the difference between them and stock piping is significant. Plus, you will be getting emission control, albeit at a reduced capacity to stock options. Another benefit is that your vehicle will not have the strong smell of exhaust fumes, which aren’t being cleaned before they exit the car.
Complete performance replacement exhaust systems
If you are looking to get the most power out of your turbocharger, then cat-back exhausts will deliver. These replace the components beyond the turbo with high-quality options that have been specifically designed for the racetrack. These solutions will enable more gases to flow, which will equate directly to more power and give you a highly noticeable boost on the track.
We have a wide range of exhaust packages available to suit leading makes and models of performance vehicles. For assistance on choosing the right option for you, give our team a call on (02) 4340 4463 or email us at email@example.com.
