If Mike Troyer did the tune, probably not - he tuned it correctly in the MAF curve so any airflow increse will automatically be compensated for - remember, the exhaust will help to increase airflow to the other side of the engine and the MAF measures the mass (weight) of the air. Mike is a friend of mine and he knows what he's doing. So as long as your MAF doesn't peg, you are probably OK. That said, what I'd suggest is - since sometimes things don't always go the way they are supposed to go - is to at least take it to the dyno and check the A/F and log it to be sure the MAF is still OK. If it isn't than have it fixed in the tune.
mike hasnt tuned the car yet, it just has the chip tuned by paxton (diablo) so its probably at 330 hp right now, so will the MAF be able to compensate for the exhaust or should i just forget about it for now? because im leaving for school and will not be in a place where i can get a dyno tune unless anyone knows a tuner in around Searcy/Little rock arkansas. thanks
