FZ1 exup motor and cables

[slappy]

I have had 3 different aftermarket  end cans on my FZ1 since I got it. I have not noticed any difference in performance of any kind with the exup removed and when I first bought it it still had the original exhaust and exup on.
Most people on this forum with a FZ1 have put an aftermarket can on and I cannot remember anyone saying it affected performance.
Something might show up  on a dyno but on the road there is nothing.
