How noticeable??
As was stated for cooling+ yes
" " " " sound + yes
" " " " power + yes, but......When my bike got to that 270+ it was running crappy and with the oil that hot it would never really cool down unless I shut it off for the night....
I am happy that I spent the money, it was hard earned and tough choices were made elsewhere to make them possible. But the end results speak for themselves. My bike runs faster, cooler, healthier, and will live longer thanks to the changes....
