WTF DC Header problem
Ok, last night I finally decided to install the DC Header I bought from Garm on black friday. It took about 2 hours just to get the old one off, since Toyota was kind enough to tighten every bolt on my car with the fury of a thousand suns. After getting all that stuff off, the new one went on really quick. Unfortunately, the damn spring bolt on the midpipe flange is running right into the O2 sensor, so there's no way to tighten it down. Thus I have an exhaust leak that sounds like a BBC anal pornstar farting the whole time I go down the road.
I read several threads of people installing these without problems, and the included documentation says to use the existing spring bolts. I don't see how this is even possible though with the O2 sensor sitting right over the damn bolt hole in the flange. Help?

You have a gasket in there?

I'm not real sure, would that have been stuck to the original header or the midpipe? I never saw a gasket when we pulled the old one, unless it's stuck up in the collector of the header and I just thought it was piece of it. Where's the gasket normally at?
Thanks Garm. BTW it was interesting to try to get pictures from underneath the car while doing weird acrobatics at 1am to get a flashlight and my phone up in there. It took many tries to get clear ones.

The gasket could have stayed stuck to either the header or the downpipe. Check your OEM header to see if it is in there. Based on your pics, it would appear that no gasket is in place. The header/pipe gap is far too narrow.

Fuck. Opened the box in the trunk and yanked on the end of the collector and sure enough, I left the gasket on there.
Think I can get it on the new one without taking the header back off?

FYI, I've had to replace my header gasket (with stock header and stock downpipe). Guy at the muffler shop said was common. I might suggest buying a new one just to give you a couple extra years of no worries.

I think the exhaust has some play in it, and you can get the gasket in there without removing the header.
I think the gasket will create the gap you need so the bolt fits and the O2 sensor is safe. More great pics, please.

Sweet. I'm checking around to see if anyone here at the office happens to have a floor jac in their trunk. If so I'll just jack it up in the parking lot and install it real quick. If not I guess I'll wait till tomorrow morning.
I'm kicking myself for leaving that out.

Holy crap, that thing is rough!
The one I have still looks good. My Yaris is 3 years old with 39.4k miles on it.

Got a jack, crawled up under there and put the gasket in. It's running like a BAWSE now. Thanks for the help fellas!

I'm just using a stock O2 sensor. DC didn't say anything about needing a defouler.

Hurt anything or just be annoying? I guess it can be swapped out without taking the whole thing apart at least.
