I can't figure out where in the form to put this, but I need a GMS 2000 .25 muffler.

Anyone know where I can get that?
GMS isn't being made anymore...

I remember the GMS brand, but I never owned one. It MIGHT be compatible with an OS muffler.

All you can really do is measure the bolt spacing and go looking for something that matches it.
That said, you may be throwing good money after bad. GMS engines were nothing special, which is why they didn't last. It's not worth much, even with a muffler. You'd probably be better off spending your muffler money on a current production .25 or electric system.

Thanks
