special made for me with the single round tip.. it was just a very expensive kit to buy and realize there was a defect. How about if I just deal with it and if it still irritates me i can get a discount on a new muffler section? Somthing you have in stock like double rounds? I know its somthing on the inside of the muffler but my worries are it may come loose and cause a vibration or a rasp.
