Welcome to the Volusia Riders Forum.
From what I've seen and heard, Big Straight pipes are just about the loudest pipes on the aftermarket.
I'm not convinced that any add-on small muffler or baffle will really quiet the noise those pipes produce.
If You would truly like to quiet Your M109, re-install Your factory exhaust, if You have it, or try to find a set of factory pipes on the used market.
I'm certain that a few other members will chime in here, and may have the information which You are seeking.
