All you have to do with this kit is cut the pipe 1/4" past the taper ON THE bell and reinstall the screen on to the end.make sure you deburr the pipe.

I didn't need safety wire around my screen.With just the screen wrapped around the end,the insert fits tight with a light tap of a rubber mallet.Drill a hole and install the retaining bolt and your done.I will post up a picture of the finished product when i get my camera back.

I also noticed it did knock down some of the bark out of a already obnoxious exhaust.The fit and finish looks factory.
