I used the bracket. I was explaining how I re-installed the head bolt after removing it. I highly recommend using the bracket. It will hold that muffler in place very well. I put a tiny little bend in my bracket to get it to clear the muffler and the engine while installed. I have maybe a 1/16 clearance on both sides. As it came it would rub a tiny bit on the engine or muffler, can't remember which. You really want it to not touch either one after it's installed
