I would go with the prochamber. I think you would get more hp and you also make your car sound bad!

pullies you wont feel much difference, prochamber you will feel some gains and HEAR a HUGE a difference.

I would do the prochamber. Although I felt a nice gain from my pulleys, I would rather have a nice gain, and set off car alarms with my exhaust.
