Threw mine out as I kept breaking the stubs off the muffler. I got some of that spiral stainless steel exhaust pipe from JC Whitney (flexible, what you see on old indians/harleys, etc). I ran it from muffler to muffler with a curve to miss the tire. I ran it on the outside of the stub rather than the inside. I used some T-Bolt clamps to scrunch it down over the stubs.
