Default Helix DP question

I bought a helix catted downpipe used and my hush just came so I will be doing the install in a few days. Of course I have ready every install guide I have come by. One thing that confused me is that on my DP right in the belmouth there is a bolt threaded on both sides that is hallow. It looks like something is suposed to attach to it, but I have seen no mention of it in any of the guides. Any help would be apreciated.

The picture shows what I am trying to describe.

Maybe I'm wrong, but it looks like someone perhaps had an EGT sensor there? I know when I bought my Invidia DP, it had a bung for the O2 sensor closer to the back.

I think it may be an egt sensor. After looking at a pic from gruppe-s it apears there would normally be a bolt there. The question is what size bolt (lenght and diamater) and whats the best place to get one.


Also, for furture reference when I get an EGT gauge, would that be a suitable sensor location?

The pipe comes with a plug for that bung in the bellmouth, the bung is for a wideband a/f sensor.

I hope that the picture you posted is not your pipe, because it looks like somebody welded in a different bung to fit another type of sensor.

to answer your question about EGT pyrometer placement, no, the downpipe is not a good place. The most common (and pretty easy to fit-up) place is on the drivers side exhaust manifold. There is a small casting button that is perfect for fitting the egt probe. (you will have to remove, drill and tap the manifold, but this is super easy.)

Yes it is.

I hope I can find a bolt that matches the hole or some sort of cap for the fitting. The problem is the half of the bolt going into the pipe has a special very closley spaced threads that home depot doesn't carry. They said try napa, but they were closed by the time I got there.

If I can't think of some kind of solution then I'm in trouble because I wanted to install this on wednesday, which is my next day off.


Here is another close up of the problem area. Now that you mention it, it does look like someone welded something in there since the weld doesn't match the rest of the ones on the pipe. Thanks Saucemaxx.

Doubt your going to find the right part to cap it at a hardware store. I know Napa is closed on sunday's where I live and they usually have a good selection of automotive nuts/ bolts and problem solving parts. Try Kragen or Auto zone or whatever chain Automotive store you have in Rhode Island, they may have something. I wouldn't worry to much. Just a side note, when you install the DP, for alignment purposes bolt the DP to the turbo first then work your way back or it can turn into an alignment pain in the ass. Good Luck.

that may be some kind of pipe thread.
if so, no 'normal' bolt/cap will work.
look for pipe fittings.
