hello
yeah he's not done any engine or fueling mods to his, it's totally stock.
i'll grab a picture of it when i can but the diffrence is so dramatic that you dont need a tape measure, on his the inner pipe allmost extends beyond the outer cans , wheras on mine they are really sunken in, so that they are only visable if you peer right into the end of the cans.
i can think of no idea why someone would do this, it's really odd and because the sound reverberates around the end piece (the black conical section) and sounds like a 2 stroke falling down stairs at low revs.
any thoughs at all??
cheers!
