A freebie and no replies!!! Please read!
 

I have a 2009 S-Crew, 5.5' box. Can't leave exhaust stock on anything... put a Magnaflow 18" muffler in place of the Ford Factory muffler. It is the wrong move for the driving I do (99% Freeway) and it makes the wrong noise for my ears at exactly the speed I like to travel, so.... I am offering it to anyone who wants a very good sounding aftermarket exhaust and would be willing to swap me for their factory system from the Cats back - as simple as putting the trucks on a hoist at a muffler shop, unbolting the system at the flange behind the cat, and doing the swap.

You get a Magnaflow system, I go back to stock. PM or reply if you have any questions. I am in Edmonton, could consider a road trip to meet you somewhere to do this....

Best of luck but you'll need to find someone local to make the trade work.
