The P0420 code usually is the cats going bad. Usually if u tap the cats with a rubber mallet and hear them broken up inside they are no good. I wouldn't advise on doing this yourself because I work at a Chevy dealership and ever V6 camaro that ever came in for these there's no way in getting the bolts in the manifold without snapping them even with torches. As for the P0441 you could have a leak in the Evap system or if you leave your car running sometimes when you gas up it'll set an Evap code.
