I run mufflers on both of mine, (still loud but takes the edge off) I learned very early on that the silly drag pipes were good for nothing but annoying me. I have high exit duals on the rigid and a 2:1 with supertrapp on the other. Both may get the 2:1 supertrapp next, it seems the best way for me to get any all around performance. (yeah I know, "performance" doesn't really fit the bill here........nothing like Speedy, but I never expected them to be) If you need tree stumps pulled, I'm your guy :razz:
