COuld it be??? 
So I Purchased a 99 trans am that came with long tube headers with dual 3" off road pipes loud *** hell.So i took it to some muffler shop to have them make it a lil quieter. So the "proffesional" suggested 2 get 2 resonators installed before the x pipe. couple of days later the car sounds like **** and feels like ive lost a whole lot of horsepower.it even seems like my tunes off?can the resonator i installed be the problem?please help 
Do you trust this shop in question? Check to make sure everything is on the car. I personally have a hard time leaving my car at a shop overnight.
Next check for you usual plug wires burnt or bad 02's, ect.

i do trust the shop bin going ther for many years. and i left the car ther for only 30 min.But the reason he instaled before the x pipe was cuz theres a pair of pipe mufflers after the x pipe. but i will check the wires and all tomorow when ther is more light.
If the resonators are a straight through design, I don't see it having a significant impact on on your exhaust set up. If the symptoms only showed up 2 days later and not immediately after, I would look elsewhere for the problem.
