Running a midpipe can/will lead to boost creep, which is tricky even with an aftermarket ECU or PFC. I do NOT suggest that.
I'm not positive that a new cat would cure it, but I would check it. You didn't mention any other problems associated with a plugged cat, so I'm not sure, but it was the first thing I thought of.

dont run a straight pipe (you have down pipe already ), if you put the midpipe on there with the stock ecu , there is a chance that you could get some boost creep and explode and die

The stock ECU is programmed to run rich to protect the engine. Removing the airpump and putting on a downpipe will cause the extra fuel to end up as unburned exhaust. That is why there two cats and an airpump on the car stock. I am running a DP with a high flow cat and catback exhaust with an airpump and it still smells of gas until the cat heats up.
