Einsmann makes really nice exhausts I am looking at them for my 4.6is because they have a factory style tip and I really like the way the factory tips look as well.

I have a quicksilver exhaust on my 05 masser which sounds amazing...I don't know if they currenly have a fitment but they will build any exaust you request so it may be worth checking into

also Hammann has an exhaust for your truck but it does not use factory style tips
