Quick and easy so far, I hope the rest of the transaction goes just as smoothly

Quick and easy. Did not find any hangars or brackets though. One mounting arm on muffler bent in shipping. Had to use torch to straighten it. May want to look at some protection for hanger arms or brackets that stick out. Otherwise ok.
