3" mandrell exhaust

Go for it
Makes a noticeable difference and as the guy who fitted mine said when I asked about S/S He said you have too much money.

S/S was $1800+ mild was $1000 fitted

Most if not all "Turbo" mild steel exhaust tube on a diesel will last for many years, A muffler will develop leaks before the pipe. So no benefit going stainless.

The 3' mandrell bent exhaust system will allow the turbo to spin up a lot quicker as it get the spent exhaust gasses away and free up the turbo. By and large gets heat away from the turo as well.

A great addon to complement the turbo system.

The stainless steel system will resonate more than the mild steel, I would be using mild steel and then considering High Performance coating. If you intend on keeping the vehicle it's worth doing imo.

High Performance Coatings

I have a friend who fitted a 3" Beaudesert exhaust and dump pipe to his 2004 TD Landcruiser (identical to yours). It was a very nice piece of gear, but on its own there was not much difference in performance or economy.

I think if you were to add a chip as well, there may be more benefit.

This contrasts to my 1HD-FTE 79series, where a 3" Beaudesert exhaust made a huge difference - mainly because my cat converter was blocked with soot and the Beaudesert replacement skips the cat converter.

i fitted a Hurrricane brand exhaust to my 3 ltr diesel and the difference was amazing.
i thoroughly recommend a 3 inch to your vehicle as well.

cheers.

Hi Noel,

A few weeks back I was talking to Graham H (QLD) and I am sure he said that the 3" system he had put on his TD 100 series Landcruiser was of greater benefit that the chip he had put on.

I may have got that wrong but I am fairly confident that's what he said.

He recommended I do likewise on mine and I am thinking seriously about it.

There is a lot written about 3" exhausts and all good.

Cheers, Bruce.

Beaudesert exhaust make there products from aluminised steel as standard. You will have no trouble with it rusting and in my opinion it has been the best money I spent on performance. Make sure that you get the dump pipe done at the same time as it is pointless if you don't.

I have a 2005 td Auto Landcruiser fitted with a Tipan 3" mandrel bent exhaust as well as a DT chip. I am very happy with the performance and fuel economy. The main difference I notice is when I am towing our Aussie Swag camper trailer. Fuel economy has improved ( approx 2 litres/100kls ) and overtaking is a breeze. I will never get my money back but the ease of driving I think it was money well spent.
