Domin8r Exhaust

[Hornet75]

Has anyone fitted a Domin8r exhaust from 4WD Supa centre?
Looking at putting a new system on Tricky soon, and these keep coming down in price.
I can get a Redback system at cost price, though still dearer than a Stainless Domin8r system.
Also been looking at Genie Performance Exhaust as well.
Don't want anything too loud though.
What are the brains trust thoughts?
Cheers
Bill

Sorry Bill I don't have one & do not know anyone that has one either.
What money are they talking about ? You might have to be the tester
Let us know the feedback if you go ahead with it

[Hornet75]

Stainless is $795 and aluminised steel is $695.
Seems too cheap to me.
Someone mentioned to me he's heard they are noisey

[Duck]

Are they trying to break into the exhaust market ?
I am not really up on pricing but sounds a lot for some bent pipe
Wouldn't the noise side of things have more to do with the Cat converter than the exhaust itself ?
the bigger pipe may make it sound a bit throatier, do they include a cat or do you reuse your existing one ?
Or is it from Cat back ?
I would have a frank conversation with them asking about such things as noise and see what they have to say. Let us know how you get on

[scumbag]

just drop the rear muffler.
I took the muffler off, cut the muffler part off and cut the droppy tip and welded it on as a stubbie side pipe type deal.
cost... well nothing if you have a welder... havent heard a better sounding triton yet...

doesnt drone at 100km at all, pretty dam quite at idle.

also illegal too
but each to there own

yeah it doesnt fall into the very illegal space though, honestly if you follow legislation theres very little you can do.

These are made by Berklee and they do include the dump pipe and the cat. They are 3" and I have heard that this size starts to reduce the benefits with the 2.5 deisel. Diesel Care in Tamworth even told me that it would not give any performance improvement to change the exhaust on mine.

Anyone had any other information? Is 3" ok or is a 2.5" better for performance?

[Cowboy Dave]

Those Tamworth blokes sound like they know what they're on about to me.

[buffhunt]

Can't say about the Domi8r. I have a 3" Redback on my 2011 MN. I was given a choice of 3 different muffler types. Loud, Medium, Quiet. I have the medium and I'm glad I didn't take loud. It's very throaty and at some revs can really pulse the eardrums in the rear seat. I noticed a significant gain on the highway for overtaking and a slight improvement in fuel economy. Around town/offroad, seems to be about the same economy to me. I can noticeably hear the Turbo whistle with this system now.

[docta.phipps]

So did anyone try one of these exhausts? I also noticed them and the price of $747.5 for 409 stainless with free delivery is quite attractive.

[gazman152]

Very close to ordering one of these yesterday. They are out of stock and will take a while to get some in. They are made in Vic where I live and was told it would be sent from Qld ???. Looks the goods for the money but ended up going with 3 inch Playtime exhaust. Went this way because you can fully customise the system but couldn't with the dominator. Ie - I didn't what a traditional muffler like the dominator comes with. I was chasing a better flowing resonator. $590.00 and $150 if you want it fitted. We'll see how it goes.

My exhaust comes out the side aswell and its perfectly legal even has a cat and a muffler it has to be a certain distance from the last opening door or window on a downwards angle bo more than 45 degrees( might be wrong with the angle) on the drivers side of the car

[4wd26]

each state has different regs

I looked into it and in QLD believe it was the last weld in the floor pan.

I'm starting to hear more and more bad stories in regard to the 2.5 triton engine (variable vane turbo) and 3" exhausts

they can get over boost limp modes (not everyone- but does / has happened)

this seems to happen when flooring it up a hill, overtaking and in the worst possible instance and autos are more prone

code= P1298
this provides a situation that is very dangerous as the triton looses all power

some do it some don't, some additional modifications can further limit the condition, look to prevent the overboost

[coughy]

hay 26 do you have a chip or the like done to the trity??
or even a exhaust done??
just asking not being rude

i will soon hehehe

edit sorry just putting up here that a m8 has ordered one of these $740 to the door step takes 2 to 3 weeks to get here so i will be fitting it for him and we will see what it does and sounds like in couple weeks time...

[4wd26]

yep a chip been in for a long time (like 5 years)
but my triton is also 3.2 with old school turbo

I'm also not blaming one exhaust/ manufacturer, as far as I can tell/ research, all 3" systems with the MN triton/ challenger can induce these results

[coughy]

yer ive heard of the same thing all good im going to run 26 psi so this isnt going to be a issue for me
have that sorted i hope...

[srb]

Hmm that's Interesting 26. So we're still hearing these MN's are over boosting with larger exhausts ay? I'm not surprised.

I phoned Scott's Rods years ago when mine started limping.. They told me it was unlikely to be caused by their 3" exhaust... Even now with Tonys dawes valve mod, it will still goes into limp mode from over boost... But now I have to try a lot harder.

I think ALL exhaust companies should warn their customers of this potential issue caused from a 3" system. If you've experience it, then you'll probably know just how dangerous it can be.

Once the condition is understood it can be avoided... But only from driver input.

Not all 2.5s will have the issue but it looks like we'll start seeing it happen more and more as people flock to these larger exhausts.

I certainly don't regret going to the 3" system, I've learnt to drive around the issue, but I'd hate to see the unwise get killed in a head on collision trying to overtake a truck.

[Cowboy Dave]

I thought it was past the last opening window by a certain distance? So for the glxr it's behind the rear cab window.

The 3 inch exhaust thing is a massive concern. Plenty of people will say oh mine is right as rain but you wouldn't want to be one of the poor blokes who cops a limp mode while overtaking a road train on the wrong side of the road doing $1.40. Seriously life or death stuff. The thing that amazes me is that most are doing it for the exhaust noise since it does SFA in a non modded MN performance wise.

[coughy]

hay srb do you have a map clamp in your box of tricks??
as i was under the inpression that the the new dom mk1 has a built in map clamp so the oem ecu only sees what it is spos to and the chip can push past this with out any problems???
so a 26 psi and chip with a 3" zorst shouldn't have this limp mode problem???
and yes it is a very dangerous stupid idea i have had it towing the boat
grr not fun

National Code
2.7 EXHAUST SYSTEM
Where possible, the muffler(s) and catalytic converter and/or particle trap from the exhaust system
of the donor vehicle should be used.
Where alternative exhaust systems are fitted, the system must incorporate any engine emission
control equipment, meeting the same standard, as that fitted in the exhaust system of the vehicle.
Where an exhaust system runs through an inner mudguard panel, the panel cut-out must not
weaken the inner guard and if necessary, the panel must be reinforced to compensate for the cutout.
Exhaust systems passing through inner guard panels must clear the wheels, tyres and
suspension components over the full range of travel of the suspension and steering.
Exhaust systems must be provided with appropriate shielding, a minimum of 100mm ground
clearance and also meet the ground clearance requirements of ADR 43/… where applicable.
Section LA Engines
Version 2.0 – 1 January 2011 Page 9/LA41
The outlet of an exhaust system must be rearwards of any passenger side entry door or opening
window. If any part of the exhaust system, including the outlet pipe, extends beyond the profile of
the body (other than on the underside), it must be shielded. Exhaust outlets must also meet the
requirements of ADR 42/… where applicable. Vehicles manufactured after June 1988 must not
have the exhaust exiting to the left of the vehicle.
Modified exhaust systems must not unnecessarily restrict the flow of exhaust gases and must be
free of tight bends and other restrictive components.

QLD additions
The exhaust outlet must extend at least 40mm beyond the furthermost outboard or
rearmost joint of the floor pan that is not continuously welded or permanently sealed and
which could permit direct access of exhaust gases to the passenger compartment, but
not beyond the perimeter of the vehicle when viewed in plan.

The exhaust outlet, if to the side of the vehicle, must discharge to the right hand side of
the vehicle and horizontally or at an angle of not more than 45 degrees below the
horizontal.

You'll probably be ok, best to test it on a quiet road though. Conditions when it happens are usually long hard uphill runs at over 2800rpm's, usually for more than 40 seconds, I avoid the limp by a quick off/on stab of throttle every 15 to 20sec to reset boost target.

I have older 219chipit with map intercept running a max 25psi. Only a mild custom tune with stand alone boost and Dawes back up... And yes I can still make it limp if I want.

Tony might chime in with why the VGT still runs aways.. I barely understand it, so it's probably better he explains it.

It's a very serious and dangerous issue for the people that are unaware, so I'm glad it's being discussed here... This knowledge might save someone.

[biggibbo]

The voltage clamp and Dawes valve help prevent it, but do not eliminate it. Seems to happen when towing under load up a hill. The 3" exhaust exacerbates the symptoms

[srb]

Biggibo is correct, he has very similar setup to me and was experiencing the same in the early days, It was doing Tony's head in trying to work out wtf was going on.

[coughy]

but i thought the voltage clamp stopped this issue as the oem ecu only seen what is the highest that it was aloud and there for it didnt happen any more

mmm interesting looks like i will have to look out for this as i do tow a boat and it happens now with a dawes and bleed off valve i have it ramped up
maybe a trial with the ramp off and maybe a slight ramp
i will look in to this more when it arrives...

im installing a tony dom mk1 which has the voltage clamp so lets see what happens.
have you tried no bleed of valve???
maybe the volgate clamp needs to be a little bit tighter as in only ecu sees 18psi??? (ps i know how it works)
i still have stock exhaust so lets see what it does stock then the egt's then the 3" zorst later...

but yes i have had the limp overboost a few times towing the boat very dangerous when up a hill and the shit box cuts out from overboosting have to dive to side of road and restart with no go pedal

gggrrr bad idea mitsubishi
