which exhaust would be better for a turbo II motor boosting about 13psi

Both of those exhausts are cheap and I personally think they sound awful. You may like the sound if you like the car sounding like a chainsaw on crack or the typical Honda with a fart can.

However, at 13 PSI you're out of the efficiency range of the stock turbo. You're starting to push more heat which is going to significantly decrease turbo life and make it a lot easier to pop the engine due to high IATs. Also keep in mind that you are out of the capability of the stock fuel system so you will need as set of upgraded secondary injectors, some way to control them, and perhaps a pump upgrade. An FCD is require to stop the stock ECU from hitting fuel cut.

agreed. get more robust parts for your exhaust setup. also, don't try to raise boost until you can do it safely.
