Since around 2015, most 4WD's are fitted with a DPF (Diesel Particulate Filter) to adhere to Australian emission laws. A DPF works to reduce exhaust emissions through capturing exhaust particulates in the filter. This in turn restricts exhaust flow and so can cause a decrease in power, fuel economy and suppression of the exhaust note. To increase power and enhance their note, some people delete their DPF but this is illegal and will void warranty and insurance. If you are found by authorities to have a DPF delete, you will be up for a hefty fine. So what's the best solution? The Windsor DPF-back performance exhaust. This system will guarantee you real power gains and give a superior deeper note that is unparalleled on the market. We can custom-make onto your vehicle in the Windsor workshop or dispatch to you for your own installation.
The key difference between mild steel and stainless steel is its alloying element . An alloying element is used to alter the mechanical and chemical properties of steel. Mild steel is alloyed using carbon whereas stainless steel is alloyed with chromium, the 2 different alloys producing contrasting results in durability, corrosion resistance, malleability, fabrication usability and cost.
- Is not susceptible to rust. As it is alloyed with chromium, this metal is 200 times more corrosion resistant than mild steel. The chrome in the stainless reacts with the oxygen in the air producing a natural ‘chromium oxide’ protective skin on the surface of the metal. This means that as long as this layer is undamaged, the metal is naturally corrosion resistant.
- Will last longer, that's why we offer a 10 year warranty. While mild steel is more malleable, stainless steel is a lot harder material and therefore impact resistant.
- Looks sleek. This is the simplest way to tell the difference. Its smooth, polished, silvery-white and shiny in appearance which far exceeds the duller grey look of mild steel.
- Is more expensive. Although stainless offers far superior life span and corrosion resistance over its mild counterpart, the various alloying elements (iron, chromium, nickel, manganese and copper) make it more expensive. Coupled with the additional work required to fabricate, stainless steel is the more expensive however the benefits are an aesthetic metal with superb corrosion resistance and low maintenance. Most car owners overlook the additional costs to achieve their desired finish simply because of its durability and inviting look.
- Rusts easily. Without the chromium oxide protective layer, the iron present reacts with the moisture in the air to produce iron oxide or ‘rust’. We coat our mild steel systems in a high temperature black paint able to withstand the heat of an exhaust up to 800 degrees celsius, prevent rusting for around 1-2 years. It also looks pretty sharp.
- Produces a slightly deeper note. As the wall is thicker, it creates a slightly deeper, more solid note.
