I have been searching here and elsewhere for more info on Shorty Mufflers. Some reviews and other bike forums have helped a little. But I am still not sure about them. I am wanting to get some for my S40. I am willing to repack if necessary. My current pipe is way too loud and is just annoying when on longer rides.
I took it off today to see if I could repack it or what. This is what I found. Looking down pipe from header:
Looking into exit:
It looks as if not much is being done in the way of blocking the exhaust. A layer is welded onto sides of muffler with holes in it, and some bigger "baffles" bent out into air flow. So while I couldn't see straight through it, I could see plenty of light coming through the end when held in the light. I really like the look of the Shorty and would like to use it, but if it is no way usable then I will go another route. I just figured it had to be quieter than what I currently have, even if it is only 12" and lightly packed.
If anyone has info or experience with the EMGO 12" Universal Shorty Muffler, I would very much appreciate anything you can tell me. I am wondering mainly about volume. Also, any noticeable change in air flow, power, etc.
Thanks,
Nick
