My muffler install went very well, fit perfectly. But only because I got lucky. There was a design difference that positioned the new muffler further back than the original. I wasn't sure where to cut the existing inlet pipe so I cut it as close to the old muffler as I could. Turned out that was exactly the right place. Some documentation showing that would have been nice. If I had made the cut anywhere else it would have made the job more complicated. Luck aside, I was very happy with the result. - Muffler replacement
