I am not sure Q has any more 2.0 pipes at the moment.  Im sure he will make more as he sold what he made.  I feel the Q and halls are the best pipes out there.  If money not an issue and you want something now get a halls and have it finished how you want.  I got one of the last 2.0 pipes from his first batch.  I chose it on cost vs performance perception.  It was 200 less than halls and saved me another 200 in the bling factor i wanted.

I went off the assumption that Q being a zilla nut would not develop a new pipe if it were not improved.  Everyone loved the Q 1.1 at they love the Halls.  The 2.0 is suppose to have more power down lower--more like the halls vs a higher strung pipe. I realize no dyno numbers.  I went off what others who are running them have said and the cost.

I have a shiny chrome CT pipe and new silencer I will sell you.  I have tried a bills, and a Paul Turner pipe and I like the CT much better than both those.  Im betting I will like the Q even more.

Too bad my restoration is a winter project so I cant test my Q pipe until spring.  Its -4 degrees here so riding does not sound fun right now.
