Patrol 3" Exhaust,
Well I have decided to go for a 3" mandrell exhaust on the ol girl 1999 - 4.2td but do I go mild steel or stainless steel how will the mild steel go and for how long (no salt water) my current is now 8 years old and still good condition.

Will depend to some extent on where you get your system from - having said that, mild steel is mild steel at the end of the day - but there's nowt wrong with it otherwise!

I have a 3" system from Beaudesert Exhausts in mild steel, and over here in WA I drive in ALL sorts of conditions - beach to desert - and the system still looks pretty robust to me.

Up to you whether you can justify the extra cost of s/s over mild, but if your current system is mild and and you've had it for 8 years without prob, go same and put the extra dosh into something else you want!! ;-)

dj, just expect around a 16% improvement in th 0-100kph times as long as you fit the 3" dump pipe too. Stuff all if you don't............

Two of the biggest killers in an exhaust are heat and water sitting in mufflers.

Not much heat comes out the tail pipe of the turbo's and I assume you will get a nice flow thru exhaust and therefore not much water should get trapped.

The money I saved in going mild steal I spent on a pyro and that is probbaly one of the best things I have bought.

Mild steel has worked for me. Mine is from Beaudesert and after 6yrs and 300000km it is still fine. If you are in Brissy, look up Rob Bliss exhausts in Geebung as I have heard they are very cheap but still a good job (found this out after mine was done :-(((

dj, I have used mild steel, but the front piece from turbo to muffler I had coated with heat proof coating, inside and out, to lessen the heat transfer to the cab. The original heat shield doesn't fit. I have a ute so the piece was fairly short. Also, get a pyro fitting welded in when it is made, even if you don't use it now, it will come in handy later on if you decide that you need a pyro. Just my two cents worth....
