[@davidanton6175]

Cheers for the video bro it helped a lot. took me about 12hrs to fit me 3inch exhaust on it wasn't an easy job..

Awesome mate, going to get a new stage one turbo and exhaust for my same rig!

[@jakesto72]

Instead of unbolting the turbo I unbolted the flange that’s on the turbo and took the bottom 2 threads out and then re tapped them. It saved me a shit tonne of time and gave me enough room to grab everything out.

[@RogerWilco66]

Hey Mat, I really love your videos, thanks for taking your time to share all this. I wish I could go for a 3" exhaust system on my DS22, but I guess the guys who do the annuals would drop dead when they see that the cat and the particle filter crap is missing :-) But I'm planning to at least blank out the EGR. Good advice. Cheers, Mark (from Germany)

[@kobyboatswain1762]

Hey mate, sounds awesome. Looking at getting one for my nav. Would you know how many decibels it is by any chance? heard it had to be less than 90db to be legal. Thanks for the helpful videos👍

[@mhstagg]

Hey Koby, I can't say I've measured it to be honest, though my Ute did drop out of its Rego period a few months back, forcing me to get a Roadworthy done. It passed the RWC with it on no problems, so I can only assume it was fine though I don't know the limitations of noise here. Definitely quieter than a lot of Harleys getting about though, that's for sure.

[@kobyboatswain1762]

@@mhstagg ok cheers mate👍

[@smokin4x45]

Why would you remove a turbo to do a pre fabricated exhaust made to fit like a factory exhaust.

[@mhstagg]

So you can do it without removing it can you?

[@smokin4x45]

@@mhstagg sure you can…

[@pauledwards9909]

Love the vid mate, its help me getting out the stock exhaust. 1 question. The egt sensor . the yd25 doesn't have one stock im assuming so is it necessary to get one or can you just leave it with the bung in?

[@mhstagg]

Just leave it with a plug in it mate. Unless you're adding an aftermarket one, no need for it. 👍

[@pauledwards9909]

@@mhstagg thank heaps.

[@sprit97]

Hey just wondering about that adapter plate for the stock mount you pointed out. Where you get that from?

[@mhstagg]

It came with the Kit I brought. Might not be needed for all kits

[@kyewest]

Didn’t put your cat back in?

[@Oogs1r]

Just found your video, I spent today doing this I am really struggling to get that oil banjo bolt back on I know you've done this 2 years ago but any tips that you can remember?

[@mhstagg]

I remember it being a REAL pain in the ass... From memory, I had to use a really long 3/8" extension bar for the socket wrench and hold my tongue just right... It was probably the most mongrel part of the job. Good luck! Hopefully you can get it back on!

[@alexgoold8159]

That coolant banjo bolt was a nightmare...

[@gamingwithjay6271]

Hey mate I know this video was made a while ago but was wondering if you had to re prime the turbo after putting it back into place

[@mhstagg]

Hey mate. Nah, I just bolted everything back up and started the Ute. If your oil and water pumps are working properly, you shouldn't need to pre-fill or prime anything.

[@patrickwhite8011]

did the d22 have the whistle before the exhaust was installed? or did the exhaust do that?

[@mhstagg]

Hardly, you can hear it 100% better from outside the car now that exhaust is done.

[@RBPhantomTilt]

How is it going 2 years on mate? I'm just looking at getting one of these myself. She's fucken rough but maybe some high temp sikaflex around the welds will ensure there are no leaks thanks to the horrible welds.

[@mhstagg]

Yeah, all good so far! There weren't any leaks in the welds, they just looked as though they were rushed. Not bad value really though for the price.

[@nathenpeters6681]

Gday mate enjoyed the vid thanks for the sharinging. Im lokking into getting the 3inch set up for 2014 d22, im stuck on witch one to get i keep looking at the dea with hi flow cat i dont wont to buy 1 with the hole droney sound but of course i want that nuce 3inch sound do u think ill get that with the dea hi flow cat or will it be quiet, we all want performance and u will archive that with a 3 inch im not worried about that just the hole sound with the hi flow cat cherrs mate

[@mhstagg]

Hi Nathen, In my opinion, I don't think a Cat would make a huge difference. Cat's aren't designed to muffle the sound in any way, and most modern Cat converters don't place much restriction on flow either. I'm pretty sure you'll be happy with the Cat Exhaust, but to avoid the drone, I'd still opt for the hot-dog muffler... Even mine borderlines on 'droney' with the muffler in it. DEA and playtime are much the same from what I can tell, except the dump pipe. Good luck! Let me know how you go getting it fitted! Cheers!

[@dillon9421]

Hey mate I went to change my oil filter today and the bloody thing is in a bitch of a spot, would you be able to shed some light on how to get it of? I’ve been at it for 2 hrs and can’t budge it, I’ve jacked the car and taken the tyre of and still can’t get a angle good enough to get it of. Cheers

[@sammatthews1495]

Hey man, ive got a 2012 d22 2.5L and have just purchased a 3" straight pipe for mine! Ive removed the entire exhaust minus the dump pipe and turbo, just wondering if you had any tips on how to unbolt the turbo and what exactly needs unbolting? I had a go today but couldnt crack the 3 bolts holding it in place.. cheers!

[@mhstagg]

Hey Sam. Best bet is to spray them with CRC or WD40 and let it sit overnight. You might need a breaker bar on them too. The constant hot/cold/hot tends to bind them up. Theres another product called rustof ice you can spray on that sometimes helps too. All else fails, heat the nuts up, but be careful not to heat eveything around it too much. Hope that's helpful?

[@sammatthews1495]

TheStagg already got some wd40 on them mate so hopefully helps a bit, will look into getting some rustoff ice if it doesnt work. Cheers heaps!

[@jdmden]

im looking for a new dump pipe, was just wondering where you ordered yours from?

[@mhstagg]

I brought the whole kit off eBay. The one thats included in this kit won't fit as a replacement for the original one though, they're different dimensions.

[@mitchstich9797]

How's the lift kit going for you. Any problems with the shocks?

[@mhstagg]

Hi Mitch. So far all good, haven't got any complaints. They do rub a bit in the upper control arms at full extenstion, not that they ever really get up there. But I think new Upper controls will be in the works in the near future.

[@mitchstich9797]

TheStagg cheers for the response, and thanks for making videos on how to install stuff on the nav it has really helped me.

[@BDSworldtour13]

Hey mate, do you think that could be done all from the bottom without taking the turbo off? Or will the cat / dump pipe not fit out past the d shaft etc?? Cheers

[@mhstagg]

Shannon kupfer , thanks for the message. Personally I highly doubt it. Getting the stud nuts off the back of the turbo is the main thing stopping that. Also; getting the bolts on top of the stock Cat would be difficult without removing all the intercooler piping, heat shields etc anyway. And i honestly think you'd have just as much trouble mucking around underneath with drive-shafts etc. If you manage to do it, let me know, I'd be interested to hear.

[@BDSworldtour13]

Hi again!!! How about the bottom bolt on the dump pipe heat shield? quite easily the shittest bolt placement I've ever come across. I've just spent an hour on 1 10mm bolt and got nowhere. Can't access it from the bottom either . Any ideas??

[@mhstagg]

Hey mate, Pretty sure a ratchet spanner upside down did the trick for me? The were a bit of a nightmare around the heat shield...

[@unprotectedhex1716]

Your video is good mate, helps people who are upgrading stock turbo/intercooler as well. I did this when I first got my d22 yd25, no mechanic but love working on 4wds so over time invented little tricks. To fit my 3" straight pipe I used a DEA one (Melbourne based too I believe) Replaced dump pipe only, everything else stayed in car so fairly easy. 1. Spray the fuck out of penetrating fluid on dump pipe stud nuts - 2. Go for a highway drive don't use 5th gear, or just give car a good flogging (idea is to get the dump pipe & it's studs/nuts hot) metal expands. Or if you got one (I didn't- use a propane torch but be very careful) heat rises always remember. - 3. Spray the fuck nuts with penetrating fluid again. - 4. As soon as you get home remove the passenger wheel for access. - 5. Trolley jack under the gearbox and lift it just a touch (this will move engine slightly forward in a angle giving you more access between firewall/dump pipe studs. 6. Ring panner on the nut behind the dump pipe stud (use rags to ensure it doesn't slip off under load. 7. Use a small ratchet strap on the other end of spanner and hook it up to the chassis or somewhere solid 8. Ratchet away to break the nuts loose- repeat. 9. Wiggle dump pipe off, clean threads, little cooper antisieze, reuse hardware on new dump pipe & fit. Have done this with my friends nav on his drive way too, the second time took me 2hrs over drinks because I already learned from my own painful experience 😂 hope it helps someone

Hey man, I have a nav d22 2.5 ltr 2013 model, can you tell me your experience with the 3" exhaust? I have heard different things i.e. some blokes say it's good for the engine, others say, it's bad for the engine. I am confused with the conflicting information on the net. Should I or shouldn't I put the larger exhaust in? I'm not after noise or increased power etc etc I just want the engine looked after i.e. working as efficiently as possible for longevity purposes. So what's your opinion?

[@mhstagg]

G'day Ataman, Thanks for the comment! As a mechanic, my oppinion is that a 3" exhaust, or any exhaust system that reduces back pressure on your engine can only be a good thing. The only thing that will really be working differently with a 3" system is the wastegate on the turbo, which would open sooner as the turbo spools up more quickly. Best thing you can do for these engines otherwise is an EGR block, as that stops all the filthy exhaust gas getting back into your cylinder. Keep your oil and filter changed frequently, and if you've never done it before change the other fluids too. (Gearbox, Diffs, Coolant etc) Hope that's helpfull! Cheers!

[@atamanatlas3098]

Thanks buddy, that's great to hear, I trust your opinion because A) You're a mechanic, and B) You have no hidden agenda i.e. trying to sell a particular exhaust system or trying to trash a particular exhaust system if you get my gist. Much appreciated indeed.

[@atamanatlas3098]

P.S. I'm in Vic to so if you're in Melbourne I owe you a beer, my shout of course :)

[@mhstagg]

Haha, no worries mate. I'm a few hours from Melbourne, but maybe one day I'll take you up on it. Hahaha! Good luck with the exhaust, let me know if you have any dramas. Cheers!

[@DanBarron34]

would this be the same as the yd25 d40?

[@mhstagg]

I don't think so sorry Daniel, I believe the D40 has a different manifold and turbo setup and a different dump-pipe configuration. There are probably a lot of similarities in how to fit it, but be sure to check the parts compatibility before you order one.
