It is supposed to be somewhat of a interference press fit. No gasket. When I did my exhaust upgrade, mine just popped off as well. I still think it might be leaking a little and causing a ticking noise. Unless the gap will fill up with exhaust soot, I think the only solution is to replace the Y pipe as I haven't found one on the forum. My downpipe was also leaking pretty bad as the clamp was loose. I haven't looked to see if there is an exhaust sealant type thing that might work.

Mine is solid with carbon, I am not going to disturb it.
I have been thinking about this though, and I have never tried this.
I wonder if you could possibly use something like a small strip of header wrap or muffler bandage in that joint when you reinstall it?
It would probably be a pain to get together, but would slow the leak down till the carbon could build up and seal it.

I think the header wrap is too thick but I had been thinking about some other high temp material that might be 0.010" thick. The other thing I thought about was using some of the liquid stuff. Mine has been getting quieter as I drive so I am hoping it goes away when it fills up more with carbon.
