Extra muffler silencer

Well, that's one way of doing it!  I honestly don't think the stock engines are really that loud, but if you really need to make her quieter, this is another(albeit ugly) way!


  1. Looks like exactly what I'm after! The copper tubing is easy enough, but what's your second "mini muffler" made from? Is it actually another factory made muffler of some sort, or did you put it together? How big a difference did this make in the sound? What about performance?

  2. I have no idea because I didn't build it! If you click on the text in my post, it will bring you to the forum thread talking about it.

    Personally, I'd rather build an entire muffler rather than making a strange add-on like this. Even better, I'd get an expansion chamber.
