Default Straight piping a B5 S4

Wondering what the downfall of straight piping, beside the sound you may get. Back pressure, back firing, smoking. Ive been having a ton of smoke ever since adding AWE DP's and custom straight pipe. cleaned out the pipes so it isnt old oil or carbon build up. PCV? Turbos?

Please see my thread about this issue:
