Currently the car has a full mac exhaust, shorty headers, off road h pipe, cat back. Need to get some cats on there for emissions. should i buy a couple high flows and weld them in or can i just bolt up a stock pipe?

When we had emission here I would install a MAC high flow catted pipe for the day, get emissions testing done then back to the off road pipe. I could have left the MAC high flow cats on, some days I did but when I got bored with the sound I would swap it out.
 
The higher the flow, the less likely it is to pass emissions. I would just throw the stock ones back on there to pass. I use a set of aftermarket Magnaflow 16" cats for emissions for my longtube setup.
