I did. When I bought the truck I didn't know it had a hole in the muffler so I went from that to the 24" magnaflow and I had a little more torque I thought. I went back to stock and I could for sure feel a lose of performance and I saw a lose of mpg with stock. So you should get both mpg and performance gains (just not at the same time )
Now mine is the hemi and I see you have a 4.7 so maybe a little different, but I would think you still would see both
