I've used a universal magnaflow high flow cat on mine and was pretty happy with it. I believe they make a direct fit replace for the GA as well. My magnaflow is on my grand prix now and I have a vibrant metal core cat on the GA.

I got a Magnaflow cat off E-bay and had it shipped here from a 2nd party( Tight Cali laws)
It wasnt a high-flow, It still made a substantial difference over my plugged OEM one
