Does anyone have a set of the OBX header that are not yet installed I would like to get a few measurements from you if you do? :D

hmm a couple small concerns already seeing the pics. I will do it now.

Hmm that could be a possibility, I have my spare engine on a stand and I may mock up the frame points of the engine bay, to get a good grasp as to the degree of difficulty/possibility. but I will let you know very soon.

And if you could place the two flanges together like in my pic and measure the greatest point width wise from side to side, similar to the top line in the pic on teh left. Actually eachof those dimensions or as similar as can be.

On a side note the 350z one's seem to be close to equal length headers, interesting.

Sweet that will help a great deal, I got side tracked sorry about that I will get the measuremens of the Z's headers up before long.

I got a little too lazy for paint for the moment, so the measuring tape will give an idea. after taking a look at teh on the spare engine (as close as I could get without any cutting or drilling yet) I think I am going to route out the back and come back up front as I first intended. sorry batteries in the camera died during those pics. Also when I cut the flange off I think I will have the engine out and aside so I can cut the runners down about 1/2" at a time to decrease the width and make sure I dont have issues where the collector joins. It looked like the inner most part of the collector was getting close to the widest part of the tranny's body.

See the runners that are closest to one another in this pic that nearest point
on either end is where the tranner concern is. ie there very well could be some
cutting to spec hopefully just at the ends of the runners.

The black are 350z and and the stainless steel are OBX and being that you asked this I am going to advise you to not buy a set assuming that they fit just to be safe. :)

PS Welcome to the forum there is more info on the reason I purchased these in the lusting for a twin turbp thread.
