I really like my jardine pipes, aside from the crazy amount of afterfire you get from not tuning properly  :'(. I haven't noticed any increase in HP yet either, but i'm expecting that to change with a rejet.

the sound out of it is amazing. first time i went riding with my pals (both have sport-bikes) they thought I had rolled up in big v-twin with aftermarket exhaust. both of them were real surprised to see a single make that much noise.

'course, they were also surprised when i turned her off and shot a lightning bolt out the back...
