Frequently Asked Questions

What is a muffler delete and is it legal in Australia?

A muffler delete involves removing the factory muffler and replacing it with a muffler delete pipe. While this results in a much louder exhaust note and is popular for track use, it is often illegal on public Australian roads due to noise-level regulations (typically exceeding 90dB). For a street-legal alternative that still offers a sportier sound, we recommend a high-flow sports muffler or a glasspack muffler.

Why should I choose a stainless steel muffler over aluminised steel?

A stainless steel muffler is the superior choice for Australian drivers, especially in coastal areas. Stainless steel (particularly 304 or 409 grade) offers significantly better resistance to corrosion and rust compared to standard steel. It also handles the high temperatures of a performance muffler setup more effectively, ensuring your exhaust system lasts for years without failing.

How do I choose between a 2.5-inch and a 3-inch muffler?

The choice between a 2.5-inch muffler and a 3-inch high-flow muffler depends on your engine's power output. A 2.5-inch setup is generally ideal for naturally aspirated 4-cylinder and smaller 6-cylinder engines. However, for turbocharged vehicles or large V8 truck mufflers, a 3-inch muffler is often required to reduce backpressure and allow the engine to breathe more freely under load.

Will a performance muffler increase my car’s horsepower?

Replacing a restrictive factory unit with a performance muffler can increase horsepower by improving exhaust gas velocity. By reducing the work the engine has to do to expel gases, you can see gains in both power and throttle response. For the best results in the Australian climate, pairing your muffler with a high-flow cat-back system is highly recommended.
