did you remove any sensors when you removed the pipe's as the ecu could just need re mapping ? for the changes.

Sounds like your suffering Overboost, check the wastegate arm is free moving and well lubricated, check the hose and electrical connections to the wastegate modulator

Also - try disconnecting your air flow meter and try it down the road.
Mine did this and it was a faulty AFM
