Put a 262 flat top piston in it. The 262 had a 3 shoe clutch instead of the 261's 2 shoe clutch. The 262 also had a little better muffler.

Cheapest & fastest way would be to put a new (MS-262) sticker on it.

@Definitive Dave can get you a meteor piston. Look at the top of your cylinder and see if there is an "A" or a "B" stamped in the center. Sometimes you need a bit of scotchbrite to see it. That's the piston measurement you need. The two sizes are only .0004" different, but the OEM had to do it for a reason.
The dual clutch is just fine.
The only muffler variations I've had in my hands was a removable and non removable deflector type. I've seen some have a baffled muffler as well, though I've never held one in my hands and have ported about 10 of the model.
If you have the removable deflector, remove it and use a step drill to drill out the the hole underneath to around 3/4". If it's not removable, it's a PITA. You have to cut the deflector and peel it back to access beneath. Then fold back and braze or weld. Add some coarser mesh screen while you're at it.

You can also make a gasket to adjust squish on the Saw.
On another note a pawn shop buddy gave me a 262 cheap. It's rough. No compression. Threads gone in bottom case. As my son has absconded with the long t allens I haven't taken it all the way apart yet. Tools ordered yesterday. Looks like enough meat to helicoil the threads. It's a complete saw.
