I was wondering what methods some of you used to seal slip fit headers. Is there a special gasket? I just figured, RTV(or similar) and slip the Y-Pipe on. I couldn't have more exhaust leaks from these.

Maybe you're not slipping them on all the way?

I've seen many here use double gaskets to seal headers to the heads and exhaust band clamps @ the fittings.
RTV or any silicone based sealant will just burn up..
Keep in mind headers get red hot on a regular basis..

The slip fit on the collectors I just use a band clamp to help seal the joint while at the same time, not smashing the pipe.
On slip fit header tubes I use nothing, just slide them together and go.

Just have a ball flange kit installed/welded on each collector/Y-pipe.

Get the wide easy seal clamps NAPA sells. And tighten them till you cant anymore.
