High flow cats or used exhaust system

[vipertom7]

I unfortunately don't have much money to spend at the time, but I was wondering if anyone has a new or used set of high flow cats for sale? Also, while I am at it, does anyone have a used cat-back exhaust system? If so, please send me a message telling me how much you want for it and what it is exactly. My car is a 1997 gts coupe. Thanks!

I also meant to add that the used exhaust system that I would be looking for would have to be aftermarket, and not a stock system. Thanks.
