Outback 4x4 Exhausts

Outback exhausts


Factory Direct 4x4 Exhausts started as a supplier to other manufacturers & distributors in Australia. As the original designers and manufacturers of the Redback Offroad exhaust system range we can guarantee you are buying a quality, well designed and engineered product.

In 2014 we launched our own brand for sale to the trade & general public - Outback 4x4 Exhausts is a quality product at an affordable price. Our range is primarily manufactured out of 409 stainless steel with some applications being offered in ACMS - Aluminium Coated Mild Steel. 

Unlike most Australian 4x4 exhaust manufacturers we offer 2.5", 3" & 3.5" systems - 4" to come shortly ! we offer both Turbo Back, Manifold /Extractor Back & DPF Back. With & without High flow Catalytic Converter and with or without Muffler.


409 stainless steel is a titanium stabilised ferritic material which basically means it is a steel alloy containing chromium. It contains less nickel and more carbon than 304 stainless steel. Ferritics are best suited for high temperature applications that require corrosion resistance and high strength. The principle use of 409 is automotive exhaust systems and catalytic converter shells. 409 is more workable & more stable than 304. 409 resists both atmospheric and exhausts gas corrosion. It is magnetic due to its higher carbon content.

Through chemical reaction 409 oxidizes to a slight brownish hue which aids in corrosion resistance - we always paint our Outback 4x4 systems with a heat proof paint for added protection. 

ACMS - Aluminium Coated Mild steel is a steel that has been hot dip coated on both sides with aluminium silicon alloy. This process assures a tight metallurgical bond between the steel and the aluminium coating. As with 409 we always paint our ACMS systems with a heat proof paint.

The owners & staff at Factory Direct 4x4 Exhausts have many years experience in all aspects of 4x4 exhausts, we are proud of the quality of the systems we manufacture in our Brisbane factory and work hard to offer our customers, both trade & retail, a high level of customer service.
