Diesel Tune Australia offer a range of exhaust upgrades from a range of manufacturers including Turbo back and Cat back exhaust systems for your Common Rail diesel to suit most applications.


OUTLAW 4×4 offer an ever increasing range of premium quality stainless steel exhaust systems. 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, mandrel bent tubing, a premium quality flex joint for system longevity for minimal NVH and high flow tube and muffler design. All systems are made in 409 grade stainless steel.
Additionally 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 long after lesser mild steel or aluminium coated mild steel systems have failed.
Lastly there is the price. At Outlaw 4×4 we think you deserve to have a premium quality stainless steel system at a price the others charge for mild steel. OUTLAW 4×4… it’s a crime not to have one.
