Hi Guy’s,


Just had my 2 3/4” Beaudesert Exhaust fitted, for those of you contemplating replacing exhaust but have concerns just do it, probably the best money I have spent on the vehicle other than the Dawes setup.


EGT Temps down, Turbo spools up much quicker, 80-100K acceleration times in 5th gear dropped by .75sec (worst) to 1.2 sec (best), so much better at overtaking. Seeing as it was a 2.5 hour drive to Beaudesert I had plenty of time and opportunity to do before and after testing.


Interestingly one trial on the Gateway Bridge (for those who know it) showed good results, before fitting I could hold 80k in 5th up the bridge with 350C, now I have after fitting temps of 290C and doing it considerably easier.

Awesome mate, congrats! Just in time to show it off on Australia Day!

Did you manage to get any pics of the exhaust while your Patrol was up on the hoist? Im just trying to work out if my zorst has been modified for the dieselgas tank, or if its stock so that i can just order one of these and fit it myself... Did you get the high flow cat and dump pipe too?

Cheers

 

[chuckles]

Any reason you didn't go 3" mate?

Hi Dronus,

Sorry Mate didn't get photo's of original, but I can say there is a heap more room underneath now than there was before. Yes got HF Cat/Dump. Forgot to mention earlier, quiet too.

I got them to leave the heat shield off and I did a few more mods to it when I got home, very easy to R&R now.

By the way the workmanship is superb all the bracketing, welds and bends are first class.


Hi Chuckles,

I know a lot of guy's went the 3" but I had some concerns from research (real or not) re potential overboost issues etc with larger, I was comfortable with the 2 3/4" decision and the eventual supplier, I am happy.

In retrospect, I'm not sure Beaudesert do a 3".

 

[chuckles]

Yeah I don't think they do either mate. How would it still overboost with the dawes and needle mods?

 

[LBD]

How much?

Great news, you've just made my mind up. So the next question is, how much?

CRD - Blocking EGR - problems??

Hi guys,

By now there would be a number of forum members with the CRD who have either blocked the EGR or a seriously thinking about it.

There are a number of threads / posts which talk about the benefits.

Looking at the flip side - are there any possible negative impacts from this mod on the CRD?

In some threads there are comments about possible improvement of fuel economy - I can understand the concept of cleaner oil - but I'm curious how economy can be improved.

(Yep you guessed it - I have the technical acrumen of a tube worm when it comes to what's under the bonnet - and like many others are very appreciative of the posts of you guys who are technically inclined / upright )

Cheers Guido

Okies thanks Geeyoutoo, ill see if i can find someone with a patrol who will let me have a look underneath so i can make sure its the same.

I just rang Scotts Rods in Ipswich - They do a 3" system for a patrol - $799 plus $150 postage (to Adelaide). Includes dump pipe, high flow cat and rear resonator. They have a listing on Ebay.

Intersted to see how much the Beadesert one is (roughly, minus fitting)

 

[Dampier1]

The last time a looked for a quote was around $1495 fitted. Beaudesert exhaust only do the 2 3/4 exhaust - no 3'. He was telling me there prefer to do the 2 3/4 to eliminate any over-boost issue.

I am tossing up between beaudesert and fat pipes. Fat Pipes on the North side quoted $799 fitted with a 3' and HFC dame good price.

 

[CamoSS]

Beaudesert use/do Mandrel bends also, do the other companys that are being quoted here?
Just Mandrel bends are dearer then the old press bend stuff. I don't have one yet but was leaning towards the Beauy 2.75incher!

 

[Dampier1]

yep, fat pipes are mandrel bend at the dump only- 2 1/2 but are steel pressed the rest, Its a 3' system which with the press does not effect the flow to a degree being a 3'. I liked the idea of the press system 3' for a number of reasons and 1 is because of beach work I do. The press system would last a lot longer than a mandrel bent system. Also you can have the cat off or on - your choice, so the performance and flow is still there.

 

[Porks]

Dronus, don't know about the 3 litre, but the 4.2 diesel on gas HAS to have the exhaust modified, they also have to do the same on 4.2 Toyotas to fit gas.

 

[geeyoutoo]

Yeah I don't think they do either mate. How would it still overboost with the dawes and needle mods?

More the spool up rate, my dawes was set at 15psi but spiked to 17-18psi when it came on, driving home after the 2 3/4" was fitted that spike jumped to just over 20psi (haven't adjusted it back, will see how it goes) and came up a lot quicker, that may become an overboost issue on some vehicles.

Dampier 1,
Why would the press system (if it's not stainless) last any longer than a mandrel bend, mate the 2 3/4" I have is alluminium coated, solidly built and I expect it to be still there when I'm pushing up the daisies. Have fitted and built a lot of exhausts over the years and this is one of the best I've seen.

Dronus,
$968 plus fitting.

Curious as to how the types of bends used would affect longevity? Flow would be slightly reduced on a press bent 3 inch versus a mandrel bent 3 inch but it's not like it would be noticable on a diesel Patrol!
My personal opinion is that a 3inch is a bit on the large side for a 3.0ltr, but then again I'm used to V8 petrol Commondore exhausts!

Dronus,

$968 plus fitting.

Jesus they quoted me $1135 plus fitting for dump with pyro fitting, high flow cat and full pipe in November. Might have to call them again and just go pick one up!

When the bends are formed, the outside radius is stretched, so the metal becomes thinner and therefore weaker. It’s one of the sacrifices we make for better flow, but it still should last quite a few years.

Well done Ross, you just have to get her on the dyno now.

Thanks mate, That is on the agenda for very soon, still have the numbers from last year against which to compare, only thing is Dawes etc will also be included.

I only hope I have something to crow about when it does happen !!!!!!!!

There you go, learn something new everyday! Cheers.

 

[bennoGU28]

Just use 1.6mm thick wall mandrels and it will still be there in 15 years.....

 

[Dampier1]

Hi Geeyoutoo
I am no expert when it comes to mechanics, actually way short, but when I asked the question that I am doing more beach work, I was told the mandrel bent system is a lot thinner compared to the old mild steel- Mandrel was 1.6 compared to press system of 2.5. The mild steel exhaust will last the distance

Really, this is only my personal preference to suit my driving needs and when making a decision on an exhaust, it comes down to quality. which beaudesert exhaust do.

I am still out on the 2 3/4 system or 3', on a 3ltr CRD to suit me, my last system was a Taipan 3' and it worked nicely- but that was on a DI- These exhaust systems can be expensive for the same or similar performance gains of others.

I dont really care to much on a 3' mandrel bent system compared to press system as I believe the 3' press will adequately handle the CFM of the 3ltr CRD even with the bends, Also 90% of my driving I will never reach peak throu put for the exhaust not to handle it.
So for me, it comes down to performance still, less spiking, quality workmanship or value for money and longitivity of the exhaust system
I like scotts Rod exhaust as a mandrel bent system and a lot cheaper, good quality.
Regards
G

Looks like ill need to find someone local to make something up, at least from the cat back.
Maybe get the system, and then get someone to modify it... Ill post a pic of mine near the LPG for reference.
