No Rattle!
Well everyone. We got sick of the poor gas mileage and power of the Ram. So we bought a new Cat and Muffler. 3 hours, $300 and countless swear words later. It was done.
But boy was it worth it. The annoying rattle (which was becoming part of it's personality) The sissy exhaust note. It's all gone. The exhaust has a nice deep note. Nothing that would wake up your neighbor in the morning, but it's definite defference. And the truck is a bit snappier on the gas.
The moral of the story.
There are muffler shops for a reason.
