I have a V10, headers,K&N,dual exhaust with H pipe. I have no muffler, sounds better, same gas mileage.
I consistently get 12 city 15-17 highway but that doings 80 with the wind on my ***.
No matter what you do your going to get crappy mileage.
This is my 2nd Ex, I was hoping that I would hit the lottery and get a new 2015 F350 diesel Excursion Wednesday but just checked the numbers on Mega million.
You cant buy an Excursion and worry about gas mileage.

That needs to be in every Excursion owner's signature!
