(Or sometimes in deep snow.) So I don't think your 25 mpg is really that out of line for a smaller 4WD, reasonably driven. If the muffler helps you drive reasonably, great!

PS: The only ecomods on this are inflating the tires to 45-50 psi, and removing some of decorative crap (like running boards) that the previous owner had installed.

I see the same with my Toyota 4x4, and with mild hypermiling I have hit 30mpg.
