Some of you may have had this issue. You buy a fancy 3" downpipe that is all set with a reduced flange to properly fit to a hogged out stock 1G/2G O2 housing. Just like this click

Try and use the stock nuts to fasten it down and the nut hits the side of the pipe. Can't tighten them up or put a socket/wrench to forced it on.

What to do .

Well, I found the answer. Right at my local Autozone. Cost is under $12.00 for 4 nuts (only need 2) and the adapter.






Works great, have spares, tapered to self center the downpipe and really bites into the flange.

That is amazing. I am definatly doing this next time my d/p comes off. I have to lay under there with a crows foot wrench for what seems like hours trying too tighten it.

Takes 15 seconds a nut to tighten. Worked great and 3 weeks later, came apart great and went back together easy, just like the first time.

The ONLY thing to warn you about is that the adapter stuck in one of the the nuts and when I pulled the ratchet away, the damn adapter fell and it me between the eyes. Had a black eye for a day and a lump for a week.

Dang that is a sweet idea!
Plus it covers the stud threads and may help prevent corrosion for removal down the road.

Sweet - it might even stop someone from stealing your downpipe or turbo!

Are they stainless? I've had friends with those cheap lug nuts have them rust/seize onto the lug and they had to spend hours getting them off. It was a mess.

As cheap as they are I guess you could replace them every year but I'd hate to see them seize onto the O2 housing.

I used hi-temp anti-sieze on ALL turbo/exhaust fasteners.

That should take care of that.

Quoting Dialcaliper:

This is a good idea. One of my biggest issues with dropping the transmission, is when putting the transmission back in and reassembling the car, it takes me like 45mins to get those stupid nuts on. In my case, they almost hit the downpipe, and because of that, I can't start them with a socket, since it's at a bit of an angle and the clearance is so tight. That leaves me to try to thread the first bit on by hand, but the wastegate dump tube is in the way. I always get 'em on there, but it's a pain in my ass.

that is the coolest idea ive seen so far! As turboWOP said every time i myself drop the trans i swear the hardest part of the whole thing is the god damn downpipe. I tried to keep the DP and the o2 housing bolted together a couple times but it takes even longer and if i dont remove the radiator theres risk of damage... Either way im doing this for sure! Thanks for the excellent idea Terry! This should be in the how to section just for the pure knowlage of doing this

Thanks to terry's idea it was tried on my car and no more problems =). Unless you lose the key of course! Terry is right, Ive had to pull the downpipe off myself to install a muffler underneath and dang key socket nailed me in the corner of my eye.
Terry I'll have to take a picture of it installed to add to the post. Thanks.

I have to say that this is exactly what i needed.
I swear i thought i was going crazy or i lined them up wrong.
I'm going to try it out this weekend and see if it works out for me.
This is with the stock style studs right?

If you have small kids around your house please make sure to hide the "key" somewhere where they can't reach.
I'm on the 3rd "key" now because my nephew just loves to hide my tools and conveniently forgets where he puts them.
You gotta love them though.

Yes to the stock style studs.

I don't think so for the EVO III O2. I think the outlet angle is wrong.

As to losing the tool, glovebox works for me.

This is for your cousin's car?
You're running a vband now aren't you?
Either way cool idea for a PIA problem.

Yeah, not my car. Kevin's car, but I had the same issues for the first 3 yeras of ownership.

There is not much that is stock under my hood anymore. Let me see, blocks been modified, head is modified, ALL internals are aftermarket, intake is modified, exhaust mani/turbo/exhaust aftermarket, injectors are aftermarket, trannys biult, 4-bolt rear, etc...

The only thing that is the same part that was in my car when I bought it is the fuel rail, front rack, t-stat neck/radiator, driveshaft (soon to be re-done), and AC stuff.
