Overall....if you are going to remove the resonator, I would suggest getting some aftermarket mufflers to cover the rasp.
The milage loss is most likely due to heavier throttle usage caused by your moded exhaust. 
I have a Brullen Quiet system w/o a resonator. The Brullen system is slightly louder and deeper than stock while also having significantly more rasp, especially when cold. You will experience this with an SVT system w/o the resonator and it will be even more pronounced if you add headers or do the mystery mod. Replacing the resonator with an aftermarket resonator or muffler would sound the best.
