Back from the Dyno
Went to carbcon for a dyno day with some friends. I only have a K&N Drop in and a T1R 63mm V2. Pulled max hp: 213.98 and max tq:140.92. Here is the video of it:

I have an archive with pulls from 10 different AP1s at Carb Connection from 2003-2004. Nothing recent, so the probability of a software change or a recent repair to the dyno makes any comparison suspect in my mind.
Nearly all the bone stock AP1s were putting down 200-203. Cars with Intake/Exhaust modifications normally fell into the 190-206 range. Though I was not privy to any testing with a single exit exhaust. Even with the historical data, there is no way to determine the impact of the modification without a baseline. On one hand the majority of modified exhausts will lose power throughout the power band but on the other it is generally accepted that a single will produce modest gains. Proper testing will also require verification the car was at operating temperature and should include monitoring of intake air temperature, ignition advance, and coolant temperatures. Idling the car for 10 minutes and monitoring advance should be good enough if you have a baseline.
Dynometers are not the most accurate devices even though the printouts include significant digits after the almighty decimal point. I seriously doubt this dyno has less than a 2% deviation. With my own car and on multiple occasions, I've seen variances of up to 15whp between 6 pulls on the same day on the Carb Connection dyno. (~4% deviation) Again, you need to normalize the test environment, average the numbers from as large a dataset as possible, and compare against your baseline to get any use out of a dyno. The majority of modifications to an NA car may not even be detectable.
Long story short. Twanny425 might have a baseline here if he goes back to Carb Connection again.
