Well these guys are playing by the book I suppose, I have used a bend it ourselves pipe guys for my exhaust work, and I had a split converter that they welded for $10. They did the rest of the job cheaper than I could buy parts for, muffler, rusted pipes etc. Lifetime warranty, after six years needed a new muffler, $6 charge because muffler clamps were not covered. Stuff happens, get a second opinion, the price seems reasonable for the bearings, and seals but if you are not happy with the first repair why risk a second.
