Our Options program allows you to customise some features of an Outback 4x4 Exhausts system.

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. 409 is the most common material used for modern automotive exhaust systems and catalytic converter shells. It is more workable, more stable & is more tolerate to heat cycling ( "hot one minute, cool the next" heat cycle ) than 304. 409 resists both atmospheric and exhausts gas corrosion. It is magnetic due to its higher carbon content. 409 is easier to repair than 304 should you damage a part. All our 409 systems carry a 5 year warranty.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 resistant paint for added protection. Most manufacturers simply paint weld joins, flanges & brackets - WE PAINT THE WHOLE SYSTEM FOR ADDED PROTECTION.
- With High Flow Cat or Without Cat We recommend selecting a system with a Catalytic Converter - we use 200 High Flow diesel specific converters for optimum flow. If you go for a "No cat" system you may make your vehicle non compliant with Australian emissions regulations, depending upon the age of the vehicle. This can lead to being defected & fined for your vehicle being non compliant. The difference is only around $60 at time of order however if you come back after the order has been fitted it could cost $300 or more for Catalytic Converter Engine Pipe assembly.
- No Muffler , Resonator or Large Muffler Selecting a sound option depends upon your preference & the vehicle you have. A No muffler system will in most cases be loud - the exception to this is DPF Back systems. A resonator usually offers a mid tone note & a Large Muffler a quiet note. Most of the mufflers we use are of a straight through design for optimum flow & heat dissipation. Exhaust note varies from one model to the next - what you may love can drive someone else mad! If indoubt please call us so we can run through the options with you!
- Tail Pipes Depending on the vehicle we may offer a variety of tail pipe options, side exit, twin exit, Cerachroming etc
