2.5" dump pipe off the factory turbo out to 3" down to the cat and the rest of the exhaust.
Due to variance of the dump pipe flanges fitted from factory to these vehicles, the front flange of this system may require die grinding of the holes to slot them to enable correct fitment.
Turbo back exhaust – some vehicles will have a short dump pipe / turbo outlet housing off the turbo. This exhaust will either bolt up to the back of that factory dump pipe or directly to the turbo outlet depending on the application.
Images supplied are for illustrative purposes only and are not specific to the vehicle listed. These are used to show the style and quality of the system.
All Outlaw 4x4 exhausts include: Front Pipe Assembly, Diesel Specific Catalytic Converter, Flex Pipe following on into the rest of the exhaust which features 1 main muffler. Supplied with any required gaskets, nuts & bolts.
Outlaw 4x4 Performance exhaust systems
Outlaw 4x4 offer an ever increasing range of premium quality stainless steel exhaust system, currently we stock over 60 different part numbers from early GU Patrol and 80 Series Landcruiser's to current model 2.8ltr Colorado, Prado 150, Isuzu D-max and Mazda BT-50.
Most of our systems are offered as a 'turbo back' system which include a high flow turbo dump pipe for maximum turbo response, a high flow diesel spec catalytic converter where applicable, a premium quality flex joint for system longevity and minimal N.V.H. and high flow tube and muffler design in either 2-3/4" or 3", with the big boy 200 series Landcruiser boasting dual 2-3/4" into a single 3.5" rear muffler and tail pipe.
All Outlaw 4x4 exhaust systems feature mandrel bent tubing for maximum performance. The main benefit of the mandrel bend is that the tube diameter is maintained throughout the bend, this will maintain the exhaust system's capability to flow exhaust gas away from your turbo/engine without restriction, maximizing the performance increase and giving the engine every chance to respond where and when you demand.
All system built by HPX Australia for Outlaw 4x4 are made in 409 grade stainless steel. We use full stainless steel mufflers so you can be sure that under the skin the muffler is still looking and working like it should. Besides the obvious longevity advantage that stainless steel offers over lesser mild steel or aluminium coated mild steel systems, stainless is tougher and more resilient to knocks and bangs you experience when heading off road, one of the last things you want to find is that your new 3" aluminium coated mild steel exhaust is now 1.5" because of the log or rock you just crawled over, simply; stainless can take the knocks.
We offer a 5 year corrosion warranty on all our stainless steel systems, compare that to the other mild steel offerings and you will see why stainless steel is the obvious choice.
Lastly there is the price, you have all heard the old saying "the quality remains long after the cost is forgotten" and this is undoubtedly true, however at Outlaw 4x4 we think you deserve to have a premium quality stainless steel system at a price the others charge for cheap mild steel!
As we say, Outlaw 4x4... it’s a crime not to have one!

Why choose 409 grade Stainless Steel?
409 Stainless Steel is designed to stretch and flex from the normal tension loads generated by heat stress and engine vibration.
409 Stainless Steel is the best choice for your exhaust. 409 offers the best combination of long life, corrosion resistance and heat cycle endurance. This is proven by the fact that almost all vehicle manufacturers today specify 409 for their factory exhaust systems.
Aluminised Steel vs 409 Stainless Steel. Which is better?
Both aluminised steel and 409 stainless steel are excellent products for automotive exhaust applications. Both offer excellent heat resistance and both can be easily welded. 409 offers more corrosion resistance than aluminised. Aluminised steel is mild steel that has been coated with an aluminum coating. Because the corrosion resistance of aluminised steel is only a coating it can be damaged, but the corrosion resistant properties of 409 stainless are inherent throughout the metal.
304 Stainless Steel vs 409 Stainless Steel. Which is better?
409 is a titanium stabilized ferritic stainless steel which means that 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 principal use of 409 stainless steel is automotive exhaust systems and most catalytic converter shells are made of 409. More workable and stable than 304, 409 will accept bending and heat cycling better than 304. It resists both atmospheric and exhaust gas corrosion. It is magnetic due to its higher carbon content. Through chemical reaction, it oxidizes to a slight brownish hue which aids in corrosion resistance. While it does not polish well, it offers the advantages of higher strength and longer life due to its heat handling qualities. Be sure to ask for 409 Stainless for your exhaust system to get the best combination of both long life, corrosion resistance and heat resistance.
If this is stainless steel why is it magnetic?
It is commonly believed that stainless steel is not magnetic. This is true of grades of stainless that have a high content on chromium (such as 304 or 316 stainless steel) but 409 grade stainless steel is magnetic due to its higher carbon content.
I can see a tan or brown on the 409 stainless. Is that rust?
No. Through chemical reaction, 409 sometimes oxidizes to a slight brownish hue this actually aids in corrosion resistance. Under normal operating circumstances 409 will never rust out like mild steel.
