So,,is it one of these 3 things ??:
1. The market for performance Banshee engines isnt what it used to be,and just like the economy in general, builders are hesitant to try and invest in new ideas and technology ? For fear of wasting precious time and money that they no longer have the luxury of wasting?
2. They HAVE tried the new pipes,DID the R&D, and found them as a minor improvement at best ,and not worth it?
3. They HAVE NOT tried them for fear of some "repercussions" from certain "players" in the aftermarket Banshee world?
