Like most people, I like to be
well informed on things , for and against, that may occur when making changes to my motor vehicle. I am looking at upgrading the standard Nissan exhaust system with a 2 3/4" mandrel bent system from
Beaudesert Exhaust here in
Brisbane die to the many positive comments I have read from other owners.
I already have a DTronic engine management system fitted but would like to have smooth low end power (before the Turbo comes in) that some people have said happens with the improved exhaust. I will be towing a 1.5 ton Van in the coming months so want to get it all set up by then.
Do I have to take anything else into account such as altered turbo boast timings etc, temperature guages etc, etc, etc.
I am a real non-mechanic but would welcome any feedback from others who have done this change before.
Cheers,
Patrick

Patrick,
Can't comment on the Nissan other than to say you might be better with 3" exhaust, than the smaller sizes.
About 3 years ago we purchased a 3" exhaust system from
Beaudesert Ex Centre, and it made a noticeable difference to our 80 series Tojo turbo wagon. The initial fit, around rear
tank wasn't good, but I had neglected to tell them we had an after market
tank fitted. When I fronted at their premises to have the problem rectified, they spent quite some time to do this, at no expense to myself.
"I'll be back" to get more work done, when the need arises, great service.
Other than the above problem, the fit was excellent, and went onto the vehicle with little aggro.
Haven't worried about turbo boost, exhaust gas temps or engine temperatures, but then tojo's don't have overheating problems(sorry, couldn't resist that one) Feel that our economy is improved a bit, can achieve up to 8km/L, averaging close to 110kmh, on open highway, with cruise going.
Our setup is noisier than original setup, but is not what I'd call "loud". Sounds like a truck now. Don't think you'd be disappointed with your Nissan.
Hooroo...

Thanks for your comments Bob,
Beaudesert Exhausts get a big rap from most people I have spoken with. They were the ones who suggested the 2 3/4" system to I'll lean towards their experience on that one.
I have sent an email to Safari to check on the DTronic setting so will be interested in hearing from them.
The noise factor does not concern me as I run Cooper ST's which make a bit of noise by themselves.
Cheers,
Patrick

I'd be interested in the d-tronic settings too, as
well as watching this post with interest

Yeh,
I would suggest 3" would be overkill on the 3.0 litre.
I have 3" on my 4.2 but that's a much bigger donk- and even a 2.5" works very
well on a 4.2 litre.
Cheers and happy new year.

i have also fitted ditronic to my 3.0lt ,i think there was something in
the ditronic blurb about not changeing exhuast size.something else to think about
is fitting a thermoguard pyrometer to keep an eye egt temps.a very handy guage
when towing a van as we do.

Hi Toohey,
When I hear back from Safari re larger exhaust/settings I will post their reply as it may be of wider interest to other
forum users.
You mentioned the thermoguard pyrometer, I understand that it reads exhaust temps but what else. Is is just there to tell you that you are overheating and if so is it a similar set up to say a tacho where you approach a red limit that going beyond can do damange?
I have had no problems with temps and towing to date, (offroad camper trailer at 900KG) so could you explain to me the advantages of fitting one.
Cheers,
Patrick

the taco gives you a safe engine rev range,the pyro does the same
for turbo,i keep e.g.t under 700c when towing up long grades,up steep hills etc.
average running temps for me are 300c to 400c,heeps more info.on benits at
thermoguard web site.
