Muffler replacement on a '97 LeSabre

I finally had to replace the original muffler after 145,000 miles. Picked it up at O'Reilly and expected a long and frustrating afternoon of getting the old one off and getting the new one to fit. Everything is one-piece on these Buicks and luckily my Sawzall did the job. Much to my surprise, the aftermarket muffler inlets and outlets are sized to fit perfectly the exhaust pipe and tailpipe. I had the whole job done in about an hour. I have done many muffler jobs in the past on my cars but this one was a pleasant experience.
For those of you that may have to do this in the future, it is a piece of cake.
