2008 Expedition - Which Magnaflow?
I have a 2008 Expedition with the 5.4L. After researching this site I decided that a 18" Magnaflow (SI/SO) would be best suited for me. I am not sure what my exhaust pipe diameter is or what part number muffler to order. Does anyone have the same setup on their Expedition?

I believe this one should work. http://store.summitracing.com/partde...5&autoview=sku
best thing would be to call Summit, Jegs, or performancepeddler.com to double check.
EDIT: that one linked is what I was going to do on my Expy, but Summit didn't have it in stock. I was on my lunch break and HAD to take a muffler home, so I opted for a 4"Dia.x22" (impulse buy). My pipe is 2.5" BTW

I think it's comparable in sound to the 4x9x14. The round mufflers will be louder and have more drone than oval. I have considerable drone at 1800-2000 rpm under load, but is pretty mellow at speed.
EDIT:
the 4x22 fit without adding any more pipe. But I'm going to be upgrading my exhaust next week with a 5x8x14 (or 4x9x14, not decided yet) and 3" pipe.
