Put a mandrell bent 3" system on it and you'll be happy. Stainless is up to you but a waste of money IMHO, my normal Beaudesert Exhausts system saw plenty of beach work and lasted 7 years before i sold the vehicle with it still going fine. Can't help with fuel figures as i don't watch them myself, but you should notice a power gain straight off the bat if still running the original Toyota system.

Hi Ken, You don't say what Landcruiser - 78/79 series or 100 series.
Have fitted 3 of the Beaudesert 3" exhausts to the 1HD-FTE. On a HDJ79, the difference was dramatic because the cat converter was blocked on the original exhaust. On the second HDJ79 it made a good improvement in both power and economy. On the third, a HDJ100 there was a slight improvement. None of these vehicles were chipped.
The Beaudesert exhausts were very well made - they supply a cast dump pipe and the rest of the system fits perfect and is an easy install.

Ken,

Had a Beaudesert 3" exhaust fitted to a '97 80 series turbo, and also fitted a Redback system, sans Cat, to an '02 79 series.

Economy in the 80 may have improved marginally, but with a set of drawers and a 166L long range tank in the rear, there wasn't a marked difference. Certainly didn't get worse, and felt better to drive. The ute didn't appear to change, as it was heavy anyway. Has been very responsive since fitting the 3".

I fitted both systems myself, and it took longer to remove the standard systems, than to fit the new ones. You look at the new kit and think no way will this fit, it's all too big. But they do fit, and do it easily. Have a new 79 series, and will probably fit a Redback sometime in next 12 months.

Had aBeaudesert 3" Mandrel bent exhaust on my 2005 100ser TD and a Safari chip It went better and didnt blow the blacks on acceleration like it did prior to fitting. Didnt make much difference to fuel I guess

I got 10L per 100km Brissy to Coffs and back and not wasting any time. Got Av 17.5 per 100km towing just under 3T

Was quite happy with that. Dont waste money on SS even the fitter said only people with too much money buy them.

ken,
as others have said if you are going to upgrade then go to 3" and make sure you get a full bore dump pipe as part of the kit. Some of the lesser brands use the existing dump pipes which are often a major limiting factor.

Actually the dump pipe on the 100 is not a limiting factor unless you have fitted a much larger turbo.
The factory dump flows well and is not constricted like on other vehicles.
Some of the major exhaust brands also do not sell a dump pipe for the 100 simply because it a waste of money.

This link LCOOL shows a dyno for a 100 running extra boost, upgraded chip firmware, upgraded intercooler etc but still running the standard turbo.
It has a 3" exhaust but retains the factory dump pipe.
I have no intention of replacing the dump until I upgrade the turbo. Lots of money for no performance gain. Money best spent elsewhere for better gains.
