First, mine is an 09 XLT SuperCab 4x4. Also, it is my company truck so I am limited in what I can and will do it although I probably will purchase it at the end of the lease and then it's anything goes. But for now:

Has anyone found good fitting seat covers? I have the column shift and 60/40 seats.

Is there a good sounding bolt on muffler out there that I could get without changing the whole system?

I have put Black Moto Metals and larger Nitto Terra Grapplers on it already.
