What is the benefit of a stainless steel muffler over aluminised steel?
A stainless steel muffler (specifically 304 or 409 grade) is highly resistant to corrosion and rust, which is essential for Australian vehicles exposed to coastal salt air or high-humidity environments. While the initial muffler replacement cost may be higher, stainless steel offers significantly better longevity and maintains its finish much longer than standard materials.
Is a muffler delete legal for street use in Australia?
Performing a muffler delete can often push your vehicle's noise levels beyond the legal decibel limits set by state transport authorities (such as VicRoads or Transport for NSW). Most road-legal vehicles in Australia require at least one silencer to remain compliant. If you want a louder sound while staying legal, we recommend a sports muffler or a high flow muffler instead.
How do I choose between a 2.5 inch and a 3 inch high flow muffler?
The choice depends on your engine’s power output. A 2.5 inch muffler is typically ideal for naturally aspirated 4-cylinder and some 6-cylinder engines. However, for turbocharged vehicles or high-performance V8s, a 3 inch high flow muffler is recommended to reduce backpressure and allow the engine to breathe more efficiently under load.
