all these opinions of a pipe and the only person to own one is lms1977.
this pipe started its life in michigan in early '08, before it was ever on a turbo bike it was tested on a stock stroke, stock cylinder, not much done to bike.
most people are bias on the 2 into 1 pipe right off the bat, because of previous experiences with different 2 into 1 pipes. no one on this earth has ever had both a dyno-port and shearer 2 into 1 pipe on their bike back to back except for lms1977 and myself. he explains it to be much better then the dynoport was.
i know when t-5's were the best pipe, there had to be some people that thought no new set or pipes could be better, but then cpi, shearer, etc etc came out and the t-5 was left in the dust(for a peak hp pipe). pipe builders are always making improvments why would it differ from twins to 2 into 1's?
until someone has tried a shearer 2 into 1 pipe vs this pipe or that one or on this kind of motor vs. another, you have a uneducated opionion.
