This has been kicking around in my head also... It would be great to get rid of the over chassis part... the heat it puts out being so close to the floor is pretty hot on the feet/leg... as mentioned earlier, the mounting points for the 105 exhaust would be different but I can work around that... maybe. Certainly worth a look and I'm sure I could get a set of manifolds from a wreck to dummy up on the 80. Great food for though... thank you! 👍

Edit. I just checked the 105 part numbers for the Exhaust manifolds and they are the same as the 80 series... :)

It's been done before 😜 so I know it well work. The issue on this side of the pond is there's no room for the cats inside the frame.

Agree there. But saying that, even with the poor exchange rate and shipping, I'm in front with parts from Japan and UAE. I've not purchased too much from USA because of the crazy shipping cost. I don't get why shipping is so bad from you guys.

That's why I went Blackhawk arms. I dearly would have liked Delta arms, and Dave did the best he could for me, but it just wasn't worth the shipping.

I hear you. I source parts from Japan & UAE all the time.
Typically arrived to my door in Sydney faster and cheaper than Toyota can do.

US aftermarket stuff is harder! Many times I've priced stuff out, and by the time you add shipping and exchange rate, you've doubled the retail price.
Somethings I've justified the cost, very rarely though.

Back to the point, i built exhaust systems from scratch for my HDJ80 and hzj105. Both diesel. Both large 3" systems.
Both run inside the frame rail.
There is some differences with chassis brackets, but if you have welding skills, nothing major.
My hzj105 system was very quiet

Totally agree about the efficiency of shipping from UAE and Japan.

Good to know about the 105 exhaust system... something I will look into when I get back home... always good to have options but as long as I can get "off the shelf items" as its not ideal if you gotta get custom pipes made when things need replacing. That's why I'm not a fan of custom exhaust... try getting a replacement in the middle of nowhere.
 
Just came on. I'm in Wyoming and my '94 has leaking head pipes and the O2 sensors do not like it. My Toyota mechanic said they need replaced but Toyota does not supply them. I noticed that nothing was said about the O2 sensors which he said to replace. Also, being in Wyoming, there is no emission testing so tempted to scrap the cat. I see my local muffler shop tomorrow and see what he can do as I does some custom bending. I will be checking out some of the links shown. My '94 has 473k plus on it, still running good. Planning to drive it to Alaska by the end of April, done that trip many times already.

Scrap the Pair, put your O2 sensors in the exhaust manifolds, buy a Magnaflow downpipe with cat for a '95-97, block off the O2 sensor port, and have a good local muffler shop bend up some pipes. I used a '94 muffler on mine, but you could just as easily use a different muffler since you're custom from the cat back. A good muffler shop can replicate the over the frame routing of our '94. I've been super happy with mine. One big plus is you gain a bunch of clearance from the stock cats on the 94. A single cat on the '97 style supposedly works as well or better than the early style dual cats, but you could also add the second inline cat if you are concerned.

Just curious, what is your cat converter arrangement?

Do you have dual-downpipes to a combiner into a single cat with a single output?
Or...
...dual-downpipes to a dual cat arrangement with a combiner thereafter?

It is going into the muffler shop tomorrow to have the leaky sections cut off and replacements welded on, have the cat removed and pipe extensions added.
 
I was quoted $6100 USD for full OEM tip to tail exhaust replacement, and that’s if you can find it. Oof. Any good aftermarket options besides some of what what already mentioned? I am preserving my ‘97 80 so looking for stock fit and sound. Wondering what others are doing and if there’s a way to bring the cost down. Or is this one of those parts where you just don’t compromise. Damn this one stings.
 
Find part numbers. Go on local dealer online parts page and sign up for deals/discounts. Wait for email that says “we’re having a parts sale”. Enter part numbers for exhaust and receive discount plus avoid shipping when you pick up in store.

That’s what I did. The dealer parts website is always cheaper than walking in to the counter. Add an additional discount at certain times of year and it can really be a cost effective way to go.

That being said. The OEM exhaust parts are not cheap.

Hi all.
I have spoken to a few exhaust places about getting a fresh system fitted to my 80. They have all suggested that fitting an aftermarket standard system is not ideal due to not being able to get a good/lasting seal on the exhaust manifolds. I'm not sure if that is due to the manufacturing of the aftermarket front twin pipes, or if its due to the manifolds warping or something happening to the mating surface on the manifolds where the new pipes fit onto the manifold.

I'm not really interested in fitting extractors or a "performance" exhaust system, and I don't want a loud horrible sounding exhaust. It still has a genuine Toyota system fitted to it now but its due for replacement. I have been searching for a genuine Toyota system and it seems that they are available. I'm trying to get hold of the front pipe, but I can only find one for 1/1995 onwards, not 1994 which mine is. The part numbers I have found are,

17410-66010 for 8/92 to 1/95
17410-61261 for 1/95 to 1/99

My 80 is 10/94 so wondering if that falls into the 1/95 item? or are they compatible?

I'm in Australia so things might be a bit different for you guys over there but some info on part numbers would be a great help.

Thanks

Hey Eric,

I'm facing the same issue as you, and had the exact same question regarding the part numbers. I too have a 94 model, so while is says 17410-66010 is NLA, I saw pics of the 17410-61261 and they look identical... at least from what I can tell.. I cannot see why this wouldn't fit, and trying to work out what the difference is without having the pipe in front of me is challenging. What did you end up doing to solve this? I used an aftermarket from pipe replacement and the alignment is crap and it leaks.

FYI, here is a pic of the 17410-61261 model:

and a pic of an original 17410-66010. The only differences I can see is the o2 sensor shield and flange and it looks like the pipe for the newer model is stainless vs mild steel for ours. So basically you could use the newer pipe, but you'll need to get an o2 bung welded in.

Hi there Pete... sorry... I not been on for a bit... yes... seems like the 94 header pipes are NLA. I still have not changed mine as yet.
Like you... Im thinking that we can make the 95's work but it all depends on cost.

spoke to Toyota this morning, they can get the 95 to 99 pipe for $730 ex Japan. My parts guy agrees that there's a high likelihood they will fit.. you'll just need to get an o2 sensor bung welded in.
