Muffler/Cats delete mpg

I just took off my mufflers and both cats off. I was wondering, am I gonna notice a difference in MPG? The car definetly feels quicker, I just wanna know if i should expect a difference in MPG.

Not sure with just the hardware change, but people have reported a slight increase in MPGs after pipes and a corresponding tune.

Tune? Would I need to get the car tuned now that I took off the hardware?

I'm definitely getting 2-3 mpg better after a tune. Month driving sample size. 12.5 - 14.5 mostly city driving.

I'm certainly not an expert on this situation on this specific car, but don't you have to have a tune after removing the cats? I would think that your dash is all over the place without them!
