It can be kinda hard to find gaskets that match up well to the large ports on some of the 90cc stuff. I forget if it was shakerdriver or 2strokd now, but one or both of them mentioned NCY GY6 150 gaskets some time ago and that's why I looked into these. I ordered from Scooterworks, but a few places carry them. I wanted to pass this along to everyone looking for large port exhaust gaskets for minarellis. They come in 2 inside diameters, shown below. Scooterworks also tells their sizes in the descriptions if you order there.
Here is a look at the sides of them so you can see how they're constructed.
Here they are on the Peace Pipe for 90cc minarellis. They match up well to other 90cc pipes like the Phonger and YMS V8 too. Some of the 70cc cylinders even have big ports that these would work with.
I suggest ordering a bunch at a time or adding them into an existing order if you go with Scooterworks. The gaskets are cheap enough, but paying out say $15 to ship a $2.50 gasket makes them quite expensive to order in very small numbers. There's an eBay seller doing 2 for $10, or was when I looked. That's the best deal I saw for a small quantity. Below are links to the different styles at Scooterworks.
Just wanted to share what I've been using for leak free exhaust gaskets. They are actually for onan generators and fit perfectly between the studs with a ID of right around 30mm and one side has adhesive. Onan part # is 154-2805

Fox: Anyone who is logged in can see it but it's down at the bottom so most have either chosen to ignore it or haven't discovered it yet.
