Catless Aspirated Down Pipes/Front Pipes
Optimise your track vehicle with catless down pipes
If you are looking to get the most out of your performance vehicle for the track, catless front pipes can deliver you an extra boost. These do not include catalytic converters, so they will not filter your emissions, but they can give you around five per cent more horsepower from your engine.
All petrol road vehicles in Australia are required to have catalytic converters installed in their exhaust systems. These 'cats' are fitted to the system and look like a small muffler. They contain a ceramic block filled with noble metals that filter your emissions, removing up to 90 per cent of the harmful gases that can be detrimental to people and the environment.
These are essential when driving on the street – as Australia has had road vehicle emission standards since the 1970s, which have progressively tightened over the years.
You can get catted down pipes for your exhaust system that include catalytic converters, and they will be highly effective. They feature the same mandrel bending, extended diameter and durability that make aftermarket alternatives far superior to stock options – especially for cars with turbochargers.
However, catless pipes will deliver even more of a boost and are perfect for models used exclusively on the track. Some of those benefits include:
- Catless options will reduce back pressure in your system, which equates to improved airflow
- Higher power output and less lag
- Reduced weight and incremental performance gains as a result
- A louder and deeper sound than a catted option
We stock a wide range of catless solutions for performance brands, including Subaru, Mitsubishi, Mercedes, Honda and more. These have been engineered by leading global manufacturers, including Invidia and Armytrix, and have been crafted from the most durable materials to ensure they stand the test of time.
Gain even more power with turbo back exhausts
It is also possible to replace your catted or catless piping with a turbo-back exhaust that will increase the volume of gases released from your engine, which will equate to more horsepower. These systems start from the outlet of a turbocharged engine and run to the final outlet, which leads to open air and delivers a lot more power.
This is a significant upgrade, effectively replacing everything behind the turbo, including the down pipe, to deliver powerful boosts. This can include set-ups with no cat or with a high-flow cat, depending on your requirements. If you are looking for the most significant boost from your exhaust on the racetrack, these turbo backs deliver.
To help optimise your airflow even further, we have a range of O2 outlets and components, including extension cables, O2 outlet housings, gaskets and much more.
