I have a 1992 Ultra with the stock exhaust system. Im curious if I can cut out the left side. I want to run both exhuaust thru the one exhaust on the right side. I wasn't sure if the diameter of the pipe from where they both join to the muffler would be large enough.

 

Yes, you cut the pipe near the joint, and put an automotive freeze plug in there and weld it to seal it. In the touring section in the stickies, cheap mods, or something like that, there is a write up that has the exact size freeze plug you need.

 

Thanks.
