Right. I myself got rid of that tapered down section.

Thats the big part and not the tapered down section right? You know what i mean?

Im guessing thats the od right?

Thanks man!

OD ID is pretty much the same. the metal is pretty thin walled.

also how big (diameter) is the piping after the collectors?

2''

Alright guys, i know abunch of you are rockin these things now. How do you all like them? also how big (diameter) is the piping after the collectors?

[lateapex31]

So you gonna measure the pipes up for us to let us know if they're in fact equal length?

They aren't even close, but it doesn't really matter all that much. OEM BMW manifolds aren't equal length either, and they work fine.

To keep my line straight when cutting off the midpipes, I put a hose clamp on the pipe and traced around it with a marker. Remove the pipe and there's my line.

Remember that the pipes are stainless so have a sharp blade in your sawzall or use a cutoff wheel.

Look on bimmerforums. e36 guys are aplenty over there. I got my stock s50 mids for like 150 or so shipped. And the car went through DEQ clean as a whistle.

The headers come with a two sided sleeve. All you do is cut a factory set of midpipes to the right length (cutting off the down pips and flanges from the exhaust manifold). You leave the tapered section of the headers alone and it is the same size (ID/OD) as the factory midpipes. Sleeve goes over both ends and viola! I did it and it works great! Going to weld on some flanges eventually for easier disconnect though.

Sweet, anyone got a midpipe for sale?

What are these headers meant to mate up to?
The m3 midpipes I've seen pics of, have flanges. Will they slide on if the flanges are cut off?

yeah one pipe is tapered on the end rite? imma just cut that off on mine, and make them even, then have any decent muffler shop fab up and exhaust with flanges after the headers to unbolt them when needed...

Flanges would be ideal, but the problem is the headers are already bolted up it will be hard to fully weld the flanges. I was hoping I could get a couple stainless lap joint clamps and attach the ob2 m3 midpipe or something comparable.

I have the ebay headers from nas trader. I got them quick, and for about 140 shipped.
My question is: what is everyone using as a midpipe? Can I get some pics?
I was thinking about going 2 into one after the headers, but the offset length and sizes make it a pain, not to mention I'd like it removable.
Damn, I need to get a muffler on this s50 swap so I can drive it!

Thanks
