You'll be fine...02 sensors are no biggy, but you'll probably end up consuming more gas then needed...I've driven 90miles b4 in the rain w/ an axle that was about to break, if that makes you feel any better....lol

Re: (DC2KinG)
This code occurs when your catalytic convertor doesn't use enough of the remaining oxygen in the exhaust stream to 'clean up' the emissions. If the secondary O2 sensor picks up higher than acceptable levels of O2, it will assume that the catalytic convetor is not doing its job, which it probably isn't since you went to an aftermarket one. Running with the check engine light on will result in poor fuel efficiency as the ECU goes into default mode and tries to run the engine rich with retarded timing to keep things safe. I'd put the stock cat back on. It's not like you got any power from the aftermarket one anyways, right?

Re: (k4SP3R)
The second O2 sensor sends that code. Its only job is to monitor the catalytic convertor's efficiency. And you're correct, the primary O2 is the one that the ecu uses in closed loop mode to determine fuel metering. It is possible that the secondary O2 sensor is failing but since you said you just changed your cat, I'd put my money down on that.

That looks like an Ebay special straight pipe. Honestly if you went with a better quality high flow cat (ex.Car-sound), you wouldn't be having this problem right now.
Yeah I'm also betting that the Megan cat is tripping the check engine light via the secondary oxygen sensor. This could cause a rich condition as already stated above.
