i have a 01 929 and i just cut my slincer its a yana shiki and i took the baffle out next to the o2 sensor runs awesome notice more top end . considering the bike has the htev that creates back pressure and the ecu has addaptive fuel strategies to an extent and i know for a fact its not going to burn a valve . if it was cut off at the very bottom of the header with no htev yes i can see it leaning out . but just adding a bolt on thats been cut is not going to hurt the bike . im going to get a power comander at some point when i do the cams

 

Hi guys done mine years ago on my 06 cbr1000rr I cut about 6 inches off the back of my yoshi rs5 it now looks and sounds heaps better

 

I just did this too, I LOVE IT, it sounds amazinggg and looks so much better, thanks for the idea. heres some before and afters

AFTER:

 

did this to my F4i.. definitely worth it, those cans were HUGE.. sounded great too

 

i had the day off and decided to shorten my d&d. it wa simple reallly and i was able to keep all the stock packing in it and it looked really good not burnt out. Question tho...I installed a power commander today and was wondering what fuel map to use with this exhaust shortened?
