HOLY- $800 is WAY too much money. Wait, is that $800 parts, then labor additional?
LOL tell that guy to screw himself. Go somewhere else. That's a $300-400 job at a good shop. $200 if you go to a crappy muffler shop.

Yes, that's the 3.8. It's a good motor, but I've never seen one last that long. They develop mechanical problems later in service. If it's been babied its whole life... maybe.
