So this doesn't apply to people with single exhaust?

 

Huh. I was pretty sure the package was the same. Not to mention they sounded identical to me when I drove them back to back.

 

applies to factory duals only w/ the "quiet/mellow" muffler. ive noticed all the ones coming in our shop for the fix are mostly laramies.

 

I have a 2009 Laramie and did have the muffler rapid response taken care of. However I see that no one has mentioned the other rapid responses that need to be taken care of. The first has something to do with windshield washer fluid potentially leaking from the sensor seal. The second is being worked on my truck as I type this and is related to the first. Where windshield washer fluid weeps out is onto a wire harness concerning a temperature sensor. This harness needs to be replaced and apparently takes some time to accomplish (since I don't have my truck back yet). Also they did not have the harness on hand and it took about two weeks to come in.

 

I just got the Rapid response call last night for the weeping fluid and Harness problem last night, the tech said no big deal, just bring it in to be replaced when you get the next oil change. ( I get 3 years free oil changes) He didn't say anything about the muffler issue on mine born on 09/08.
