I recently purchased an AU XR6, and was looking at purchasing a set of extractors, i have been told by some muffler shops to remove the factory duel system and replace it with a a single sports system because the factory system with negate the extractors, is this statement true or are they money hungry? any tips?????

I don't know about money hungry, but I just got some pacemaker comp series extractors. The factory tri flow duel set up that my AUII XR6 came with was not doing the engine any justice.

I made it my own decision to put a straight through, 1 resinator, 1 muffler, 2 1/2 inch on instead.

This was only done today. Cost me $330, and trust me it has opened up my performace greatly. Gives off a nice growel, increases the flow. The old set up was too restrictive.

Thanx Mate you've cleared that right up where did you get it fitted? and how much were your extractors?

My extractors came with the stage 3PS kit from ITS Performance, so I cant give you a figure on that. As for the straight through system:
