hello chaps
was hanging out with a friend with a 660r on the weekend. we both have standard pipes (his is a '05 R and mine an '04 x) but his exhaust note sounds a lot deeper and nicer.
his pipes protrude slightly from the wider exhaust housing whereas mine are very short meaning the sound bounces around the end of the cans making a higher pitch tinny sound.

has the previous owner fiddled with my bike and shortened the inner pipe or do the X and R have slightly diffrent exhausts?

if i'm not being clear i can try to grab a picture.

ta!

Dave
