Mufflers & Catalytic Converters

About Mufflers & Catalytic Converters

Performance mufflers help to streamline your vehicle's exhaust flow, making up a vital part of any performance exhaust system. These universal mufflers are designed to fit onto the end of pretty much every exhaust system, providing an ideal replacement for anyone who wants to take their car's performance to the next level.

How Universal Mufflers Work

Performance mufflers are designed to work with the sound waves produced by the engine in order to cancel out much of the noise produced without negatively impacting on performance. The muffler is a vital part of every vehicle on the road, from passenger cars to heavy duty vehicles. With a regular muffler that's fitted by your car's manufacturer, noise will be massively reduced in order to achieve normal levels.

In order to reduce exhaust noise, mufflers normally use a winding channel which reduces the rate at which exhaust gases leave the vehicle. Performance mufflers streamline this part of your system, creating a much more efficient flow of gases out of your vehicle's engine. With a universal performance muffler, the reduction of noise will also take place but will not compromise the engine's overall performance.

How a Good Muffler Can Benefit Australian Drivers

Muffler upgrades might seem a little bit inconsequential when compared with a full system overhaul, but at they can still play a vital role in enhancing the experience of pretty much Australian who really loves to drive. In addition to the performance upgrade that comes with streamlining your muffler along with the rest of your exhaust, a performance muffler is the main factor in producing that distinctive, powerful growl that comes with proper performance cars.

Each of these products are weld-on and come in high quality, polished stainless steel, the result of endless development and local engineering. They come in a huge range of shapes, diameters and inlet sizes, making them as easy as possible to attach to pretty much every exhaust system.

About Catalytic Converters & Test Pipes

Catalytic Converters have long been the bane of many performance-oriented drivers. A legal requirement on many vehicles, they've long been bemoaned for the effects they have on the engines of performance cars as they restrict exhaust flow out of the engine. Now though, that problem is no more.

How Performance Catalytic Converters Work

Catalytic converters work to neutralise the harmful exhaust gases that are generated by your engine before they are released into the atmosphere. Much like any other filter, cats also restrict the amount of air passing through them, which can significantly reduce engine performance. Your engine can only perform as well as it can expel exhaust gases, and as such many exhaust upgrades intrinsically come with some form of catalytic converter upgrade too.

Performance cats are made specifically to ensure that while your vehicle's harmful effect on the environment is reduced, your performance isn't. In order to do this, performance cat converters utilise a high flow design to optimise exhaust flow while neutralising the same gases as before, meaning your engine can get more fresh air into it's chambers.

How a Hi-Flow Cat can Benefit Australian Drivers

Performance cat converters form a vital part of any exhaust upgrade. While many exhaust systems are of the cat-back variety (meaning your stock cat is left in place), a high-flow cat can prove a handy add-on to boost the performance of your new exhaust system without having to invest in a header or turbo back system.

Performance cats also ensure that while you may be maximising your vehicle's performance, the harmful effects that a powerful engine can have on the atmosphere are kept to a minimum, meaning you get great performance and a karma boost along the way.
