Job finished. The old system almost fell off on its own. One problem: the flange around the cat outlet split in two. I managed to replace it with a 2-piece flange that matches the muffler side perfectly. The rear muffler is a little short, as the hangers have to stretch quite a bit for the front and rear muffler sections to join properly. I definitely needed a new metal gasket between the cat and front pipe, since both ends are flared. Its very quiet.
