You're right about the 250's exhaust being different. I took the end cap of my XT250 thinking I'd see if something like the Z1 mod we do on the 225s might work. Granted I didn't go further than that, but with the end cap out of the way the visible inside of the muffler was nothing at all like the exhaust system on the XT225. There's no obvious way to drill things out in there and come up with something that works like the Z1 does on the 225...

The voyage of discovery that truly matters is not in seeking new lands but in seeing with new eyes.
