Hi Guys and Gals...

Heres a quick question in regards to diesel Patrols.....We have the standard DX Patrol 4.2 Diesel 99 model and we are thinking of putting a turbo or supercharger on it at a later stage, but for now I was wondering will a 3" mandrel bent exhaust system benefit the standard engine before charging it or is it better to wait until the whole system is set up?...I have been told that making any engine breathe better increases it power/torque which makes sense.

well jester if you put it this way, the 3" exhaust isnt going to hurt it thats for sure and yes it will be a tad benificial for the engine but it will all come into its own when you do put your turbo on.......have fun!!

Hi Jester, if your looking at the supercharger fit extractors as well every thing you do helps add to more power and tourqe also 2.5 inch exhaust is all that you need and fittingt a straight through muffler will give unbearable noise in the cab, i fitted a v8 stainless ford muffler and got the same benefits also running finer filters helps heaps a bit messy but very good filtration, this is the set up i have with a snorkel and have found it to be far superior than fitting a turbo.

For the price of a good mandral bend exhaust, the advantage will disappoint.. Put the money towards a DTS system...

Good 3 inch system when I priced before the turbo was between $750-1000, depending on where you went to... Have heard of cheaper since.

Extractors were $400, so all up thats 1/2 a turbo!

I've had a 3" straight through system put on my 2000 4.2 T/D and it did make it better low down in the rev range.
On my previous truck, a GQ, I had a Safari Turbo put on and it came with a 3" exhaust system as part of the package.
The only thing you might need to consider at this stage is that you may be up for some modifications to your new 3" system when you put the turbo on later (ie: it will have different connection to the current manifold. But I guess that would not amount to any great drama.
If it was me I'd hold off and get the whole job done at the same time.
Good luck

The DTS kit comes with a 3" pipe up to the first flange, so it might be better to wait till u fit a turbo, unless you go the s/charger, i have extractors here for $150, and can post them anywhere.
