is it coming off the exhaust manifold? If it is I don't know what it is for, but Mine was starting to rot bad so I cut it off and welded the holes shut a year ago, haven't had any ill effects yet.

It has to do with emissions. I'm thinking it might have something to do with the o2 sensor.

I also have it on my '88 YJ .. but my buddies '87 did not have it. When I got his engine into my Jeep, I kept that pipe thing .. made no real different in the drivability.

His Jeep now sports a 350 under the hood!

It's part of the smog system.
