3inch Mandrell bend exhaust
Submitted: Sunday, Jan 08, 2006 at 10:52
just wanting to hear from people who have put one of these exhausts on their vehicle before I fork out the $900 for one.
It is going to go on a 2000 nissan patrol 4.2 TD. Is this worthwhile doing????

I hope so mate would like to do same to my 98 4.2 patrol. they say you get better fuel economy and power. My brother had similar fitted to his 75 series troopy he could not believe the extra power it gave his truck.
From a engineer's view the better the air flow the better your truck will run, a snorkel
with a ram intake will help also.

Definately better power, didn't do jack for my fuel economy.
Tell whoever quoted you 900 bucks to go jump, not sure where you live but I just had mine done at Rob Bliss exhausts in Geebung (bris), stainless steel bends in the system and had the dump pipe done also, $670.

Is the whole system stainless or just the bends?

Just the bends.

Yep does make a huge difference. Many thanks to Steve how helped me make the decission.
I've put on the exhaust from MTQ (approx $490) plus a cast iorn dump pipe (approx $200) all fit exactly to the existing mounting points.
Also boosted the turbo pressure to 12psi and slight mod to the fuel. The difference is fanbloodytastic. Fuel economy is the same but certainly much more grunt. So for less than a grand you get the best performance increase you'll ever get for as a ratio to $$.

What did MTQ charge you for upping the boost. I have had the Motson 40% upgrade done to my 4.2l Patrol and the difference is outstanding however on the endless search for more power if MTQ will up the boost a little over standard and it doesn't cost the earth the I am all for it. ( Motsons won't).

From memory he charged me $150 to up the boost, set the fuel and make a couple of small mods to the exhaust tail pipe. Though with the 40% increase I think that's all accounted for in the turbo upgrade. I think they basically take it to the limit with EGT and then unless you can cool these then that's the limit.

I agree with all the others too. Except I now know I was ripped off!!!! I bought a dump pipe from Glen Binskin for $220- and then got the rest of the system fabricated locally here in Kadina SA and that cost $900-!!! So all up I parted with $1,120-...chit, chit chit!!!
The increase in low down power was most noticeable. Also, I firmly believe the free-er flowing system assists greatly in keeping EGTs down.
Since then I have changed the turbo over for a bigger Schwitzer 'dry' turbo....bear in mind that the one that the 4.2 has as standard was originally designed for the old 3.3L MQ Patrol from the 80's.
No improvement to fuel economy though.

Not that I can afford to do it , but out of interest, has the larger turbo made any difference to the power?

Yes mate, there was a reasonable increase in power although this is only "seat
of the pants" feel, as I haven't had it back on a dyno since then. They also cranked the boost up to max of 15psi.
The other saying I was trying to think of.......
"When a man with experience meets a man with money, they end up swapping places" ;-)))

Thanks Roachie, should go well at 15psi.

Like all the others.
Helped mine no end, but bugger all for economy.
Seems when one has extra oomph one uses it.

Why bother with mandrel bend on a low performance motor like a 4.2 Diesel??
Maybe if it was a high performance engine where every neddie mattered it would be worth the effort, but save ya money and just go with the normal 3in system

Best $660 I spent on the car so far. From MTQ supplied only and fitted myself. Pretty easy if that way inclined but be careful with the dump pipe to turbo nuts and studs as they are a bit dificult to access and might be damaged if not careful. I replaced mine regardless for a few extra dollars

Have 3 inch mandrel on 2003 4.2 Patrol. Cost all up (supply and fit - $650).
Didn't do much for the fuel but there is an increase in power.
I'm happy with the result, not interested in some peoples' opinions

I've noticed throughout the Forum
that a few members are experts on every subject. such as the use of generators, fridges, tents, tracks etc
Most of the comments about problems with specific vehicles (regardless of make/model seem to come from people who don't actually own one of the vehicles for which comments have been solicited but feel they need to make their presence known on every subject..
I don't own a Toyota and therefore don't feel qualified to comment on them.
If the Nissan 4.2 is underpowered then that's my problem. Can't see what purpose Trucksters comment served.
As far as I'm concerned I'm happy with the power of the vehicle, the build quality etc.
A lot of people ask genuine questions because they're looking for advice not some stupid comments

That sounds like a fair cop to me and you have thought about your position, unlike some who simply react and escalate the problem.

guppo make sure you get a kit with the dump pipe. As is mentioned above the nuts from the turbo onto the dump pipe are not easy to access but mine was fitted up on Christmas night. The lunch was big enough too.
Mother Claus shone nicely towards me with that. Not sure of economy but a 16% lower 0 -> 100 kph time if I was to use that all the time I guess the economy would be worse.
You see, I didn't order mine or deal with the people, but the sticker on the back says Beaudesert

Mine sounds "different", but I wouldn't say "louder".
The new turbo is different though.....you can here it whine at various times....sounds really kooool.

Can hear little more turbo whine when on the gas with windows down but nothing antisocial

I'm going for a 3" system i've seen all this hype about the Mandrell bend, can someone please explain the advantages of the Mandrell bend.
So far for the Disco in Sydney
$800 to $900 fitted is the best i've been quoted, funny thing is if i want a 2 & 1/2" it's only $335, considering this is standard on the Disco i won't be getting that.
