Jeff, the manager, had my car on the rack, repaired, and paid in 20 minutes. Now, there were no appointments ahead of me, so that made a difference, but I was impressed. The Subaru mechanic said they would have to order and replace all the way from the manifold back, to the tune of several hundred $. Jeff looked at it, said the diffuser was shot, and that he'd replace it with a glass pack, and it was considerably less than a hundred $.
The car was so quiet as I was leaving that I nearly stalled it! If you need muffler work, go to Jerry's.
