How open is your exhaust? Just the mufflers deleted and restonator changed? What about the rest of the exhaust? If it's still stock size, I'd advise replacing the entire exhaust, starting with new cats and going all the way back. Also, if you have the time, might not be a bad idea to port your exhaust manifolds, whether you do it yourself or track some down on SCCoA.
If you have changed all your exhaust to a bit larger than stock, you should be OK. Otherwise, if it's just deleted mufflers and changed resonator, I'd personally be a bit cautious when putting on a 10% OD pulley.
