    Theoretically the extra intake extension would make your powerband even lower. Does it? Counter to that powerband you have a very short exhaust length before the expansion chamber which is only good for very high rpm power. You should put some pipe length before the chamber to match your intake.
     
  4. hi jaguar i had some really good torue on my there chamber the pipe was 18" long but i want torque and speed and boy i find it on the new chamber it was holding the bike back but when i opened up the exit hole to 5/8" and add a pipe and muffler she doing well over 45 mph i'm going to try to make a video today yes i lost some torque not to much:cool2:
