Nissan 4.2 TD GU 3" inch Exhaust

$1200 sounds expensive, I know of one place here in Brissy selling it all for under $900. Last check was $670 for pipe alone but that was some time ago.

It is well worth the money if you get it for the right price.

Cheers, Trevor.

Moggs just spent a little more than that and reckons its worth EVERY penny

dj P, I fitted a Beaudesert 3" system to mine over a year ago. You are talking the 4.2 td, but you talk header too I see. I presume you are talking about the dump pipe that comes out of the turbo?

I thought the best way to test any improvement was to test the 0-100kph and bearing in mind the weight I was carrying I still think is was a good way. The improvement was 16% off the time only two hours after the first test. The improved time is in the ball park of where Moggs was told I understand for the exhaust alone.

Make sure you fit the dump pipe as that is very restrictive on the 4.2 TD. I measured mine at 1.7" internal and it is hanging on the wall outside if you want to see pics.

Worth every cent, it will be the cheapest and fastest improvement you do.
Do a search on here there id heaps on this discussion.

G'day djpatrol, I had a Genie 3" - including dump pipe - system fitted last week for $1200. I'm sure if I shopped around I might have saved a couple hundred (maybe more?) but this place was recommended to me by my mechanic so I didn't bat an eyelid. Worth every cent.

Cheers

G'day dj Patrol

I had my 2005 engine done late last year - 3" pipe and a new dump. Came with a engine dyno and tune for about $1200.00. Worth every cent mate. An extra 1/2 a gear at least

Had my TD42 done by ATOC in Melbourne 2 weeks ago - absolutely wrapped with it.

They installed the Beaudesert 3 inch exhaust and dump pipe, boost controller valve, Thermoguard digital EGT, closed the turbo pipe cross-over blow off valve and did a tune (boost and fuel). Cost about $1,750 in total, including about 6 hours labour. Exhaust and dump pipe by itself was just shy of 1k, EGT was $265, boost control valve $125 odd, the rest of the cost labour.

I reckon you will get a good result just doing the dump and exhaust, but it is also worth getting the boost and fuel adjusted to make the most of the new exhaust. Mine now runs boost at 15 and has the fuel set at medium boost. Apparently on the Series 1 4.2's the pump can only be set at low / medium / high boost.

As for the EGT gauge, I am towing a camper and it was recommended to get it installed if towing. Not sure it would be necessary if you were not pulling a large trailer. If I give it a bet of right foot the EGT gets to high 300's - can't seem to get it much higher than 400.

The Patrol now runs brilliant. ATOC reckoned it was between a 25% and 30% increase - and I have no reason to doubt it. It is without a doubt the best thing I have done to the Patrol. The only thing now is to get used to the turbo whistle, but I can live with that :-)

Buy the beaudesert Dump, as most places will charge you a bucket of $ to make it, and then shop round for the rest of the system, you will save $100's... my 3inch system is $500 + $200 for BD Dump.

Is it worth it - the Dyno next to AWILL4X4's work got 10kw with just a dump and exhaust, no pump work. with pump work too, you can gain 30% on original.

if you really want power, go with a ballbearing turbo setup, which is round $5000 all up, then flog your stock system for round $1500 to recoup some of it. You can get up to 200kw at the wheels with that setup.
