The end flares out to 1-5/16". Use #B91XL for a muffler if needed.
Due to the bend, you will need to do some modification to run this muffler. The inside stud will hit the pipe. You would either need to stack washers or stack an exhaust flange. We suggest the Header Pipe Allen Bolts with Safety Wire.
