Alternatives for DT headers

[Jblueskull]

I have a 2004 Lx470. My headers have been leaking for a while now and I’m starting to get sick of the extra noise. Since it seems like Doug Thorley isn’t making the headers for the 100 series anymore.
Does anyone know any alternatives that are reliable and worth the replacement or should I just go OEM.

I didn't know dt wasn't making headers for the 100 series anymore, that sucks. I had that on my list

Thread '2UZ-FE header options that ARE NOT Doug Thorley'

Mar 4, 2026

I want a set of DT header for my 2000 LC100, and will buy a pair if anyone has one, but it seems they no longer manufacture them I am looking for alternative to fix my crack header and exhaust leak. I might just get the DORMAN set off ROCKAUTO for 200 per side. I know that is just a band-aid and it will prolly crack again, but with OEM at 500ish per side and will also crack idk what to really do, if the OEM headers lasted 300k then the truck would be at 600kish by the time they need to be replaced again. They extra power and sound form the DT headers would be nice but not necessary...

hol up

why's that specifically say LHD? Mine is RHD but I don't think the headers are any different

edit:
Well I see that they have RHD version too, I just didn't think there was a difference

they don't ship to US

I understood that they DO ship to the US but you can't use the site to order you have to go through their customer service team.

I ordered these yesterday

Was checking out some install videos- those headers don't have the EGR escape? What do you do about that?

Did you get these installed? and if so, how did everything go?

Yeah, they're awesome but I hated the install

Thread 'LC100 headers install and tcase regear'

May 24, 2026

Both the parts for my transfer case and headers are arriving this week, which is kind of unexpected since the gearset was on backorder. Initially I was going to do both of these jobs seperately as I am not a super experienced mechanic and they both feel like large jobs to me. I'll be the first to admit that I wildly overthink things, but is my logic right in thinking that this will be easier to do both at the same time?

oh i see that thread now...wow what a write up. thanks so much and will now start reading it

I ran into the same dilemma earlier this year, I searched endlessly for headers once my stock ones needed replacing but couldn't find anything since the DT's were discontinued, I ended up just picking some new OEM ones up, my thinking was if they held up this long it'll be good enough

However while I was searching I emailed XAT Racing down in Florida and they came back to me with this

As you can see by the date this was quite a few months ago, if you're interested I would totally reach out! they're really awesome guys

FYI, the Rhino headers are listed as being "coated steel". The OEM manifolds are likely 409 stainless steel; DT headers were coated 304 stainless steel. Basic steel headers will rust out much quicker than the OEM or aftermarket stainless options will (even with a coating) - much like non-stainless fasteners on the exhaust system are rusty within a year or two. The heat just really degrades mild steel and speeds up corrosion.

Unless you live in a very dry climate, I'd suggest waiting until someone makes a stainless set of headers for the 100 (or seeing if Rhino would produce them out of stainless). I have a set of coated 304 SS DTs on my GX470 and they still look great after 5 years, and they see road salt every year.

hahah well, after installing the rhino headers, they can stay even if they fail. I'll never do it again

the good news is im driving ~6k miles a year so I'm not too worried about it regardless

DT long-tubes took me ~22 hours on my GX470. I'm also in the "never do it again camp" .

If you are in a dry-ish climate they may last a number of years, especially with low mileage like that. If you are driving it in the winter in the Northeast or upper Midwest something they may literally rust out in 2-3 years. That is the reason Toyota and almost every other OEM has used stainless on all exhaust system components for the past several decades.

mine probably took around the same time too, but because I was making a lot of mistakes and approaching it from the wrong angles. Also was regearing my transfer case at the same time and that was very distracting and time consuming. With the knowledge that I have now I think it probably could be done in a day, but I'm still not doing it again

The rhino headers feel sturdy and heavy, seem well made. but remind me in 3 years and ill let you know how theyve held up
