the muffler or exhaust opening on the engine. It should just pry of with a little effort. I did make sure there were no gasket pieces left behind. I placed the bolts through the flange of the new muffler and then slid the new gasket over the bolts. You can use a exhaust gasket sealant just hold it place while you place the flange in place and not have to worry about gasket dropping off. I just held it until I got the flange in place. I started the bolts by hand using the socket and extension. I alternated from each bolt until I had tighted it down. You can look up torque specs. I just used my grunt meter. It is good as new. Parts were OEM replacement. Not knock off almost right parts. I got very lucky when I found this company and will use them again.
