70s here we come. Mr. Carter or Mr. Bush, I think George is sticking it to us little guys worse than Jimmy though.

Alright to get back on topic.

So the 07 HD rams 2500- 5500 will not have this new muffler/filter? I am about to trade my 04 3500 in for a new 5500 if it comes out this year, however if it has that new muffler a F550 with the cummins sounds more appealing as long as it does not have it also.

 

As far as I know, the muffler will only be on medium and heavy duty truck, not light duty. With the 5500, it is a toss up.
