Muffler for 1-1/4" pipe????

[TractorGuy]

EDIT: Just realized Walker doesn't make one that small but leaving post for others needing 1-1/2" or larger.

I used this to find mufflers for my LMSC a while back. Got a part number I thought would work and ordered from Oreilys. Had them the next day at 7:30 AM. Little tiny mufflers knocked my 351W from 116 DB to 98. Track limit was 103 so I was golden.
