I am fixing to trade my 07 sport trac in on a 07 expedition EL. I was looking at performing some performance upgrades already..lol...I was wondering if anyone tried or heard of putting a 6.0 powerstroke tailpipe on a expedition..of course if it is a long bed...jus wondering...I see on craigslist folks are selling tailpipes for cheap and that would definately out flow the stock one because the larger diameter...thanx for any infor...
