GU Exhaust Upgrade

[Wreno]

Hey All

Hope you're all doing well

It is time to upgrade the exhaust on my 2001 3.0L Patrol - found this little guy after hearing a strange rattle!

So was forced on me but something I have been meaning to do. Currently it is welded together as temporary fix.

I have been searching the forums and based on member recommendations, I have compiled the following list :
(prices are approximate)


Taipan : $1600 (installed)

Genie - Stainless pipe system : $995
http://genieperformance.com.au/produ...-2011-exhaust/

Dinkum : from $777 (configurable with or without cat converter, muffler or straight through etc)
https://dinkumexhausts.com.au/shop/3...ol-gu-3-0l-td/

Domin8r (4wdsupacenter) - stainless steel - $747.50
http://www.4wdsupacentre.com.au/domi...2000-2008.html

Beaudesert Exhaust
$1135 Aluminised Steel, $1800 Stainless steel
* note: they supply a 2 ¾" exhaust : "outperforms most 3" exhaust systems which are fine for the 4.2L GU but too big for the 3.0L GU"
http://beauexhausts.com.au/

Would anyone rule out any of these products / companies? Any other companies that stand out?

Most of the sites say around 4 hour fitting time (DIY) - that sound about right?

Thanks for your help

Cheers

I think the Taipan is ceramic coated isnt it......?

would explain the hefty price

Try Scotts Rods as well

Updated Beaudesert Exhaust quote.

Taipan - that price is installed too I believe - will update post

[Bigcol]

atleast Beaudesert explained why you shouldn't have a 3"

and it is correct 2 3/4" is better for the 3L than the 3"

although, at the price (1800 V's 1600 for the Taipan) was the Taipan quote for the 304 stainless or the mild steel?

if it was 304 stainless, I think I would lean towards the Taipan

get another 15 years out of it (hopefully)

Why do you want stainless? Unless you need it to be you are throwing money away that could be used on other mods. You will get zero extra performance from a stainless pipe over an aluminised pipe.

I have a Dinkum pipe, they make the pipes for the Redback Extreme series. The difference with dinkum is they use a 3 bolt flange, compared to 4 bolt on the Redback, less paint on the pipe after its made and different hanger brackets.

If you can fit it yourself you will save a few dollars too. The bigest pain it bolting up the dump pipe. The rest is quite easy.
Also im going against the grain here about the pipe size. 3inch all the way. The less restriction the better. You dont want any back pressure at all. A free flowing motor is paramount for performance.
I cant see how 3inch is too much for a 3ltr. When i had my 3ltr, the 3inch system in mine was good. Then i removed the large muffler from it. It was so much better.
So one would think that if a 3inch is too big, by removing the muffler it should have made it worse, not better. My 2c.

From reading here from others it appears the 2.75" BeauDesert exhaust suits the CRD motor better.
The mighty Di can handle the 3" exhaust

Yeah, I dont think I can justify additional costs for stainless steel - the Domin8r stainless steel price seems to be good to be true!

Was leading towards the dinkum for the price, service and configurability when you order.

I am thinking a straight through setup as I dont imagine the 3L gets too crazy loud? Mudski, how was the sound on your 3L when you removed the muffler?

Not loud at all mate. Had a nice kind of whooshing sound to it when you put your foot into it, but no way was it loud or droning in the cab. Even my TD42 has no muffler and thats louder, but still not like a petrol motor loud would be.

People advise against the 3 inch on the crd as it is more likely to cause over boost than a 2.75 inch exhaust. Easily fixed by Dawes valve. There is no guarantee that the 2.75 wont cause over boost either.
