I want to replace the stock exhaust system but I can't decide if I should go with a muffler delete and a new down pipe and maybe a glasspack, or just a new exhaust system from magnaflow or similar.

I'd go with a kit made by a known after market manufacturer myself. I hear the borla exhaust has certain ground clearance advantages over the magnaflow.

Borla made the gmpp exhausts for the cobalt. They were the best sounding exhausts hands down. Go borla
