All that it really is going to do for you is better sound(or just a loud racket depending on how you like it) and lower egt's. Other then that, it shouldn't do anything.

I have MBRP 4 in. turbo back with cat delete installed with muffler and I am noticing 1.5 mpg gain (hand calculated) so i don't think you will have an issue with losing fuel mileage. I am also going to install muffler delete in next few days.
