i got it from webbike japan, its not low, u will be ok goin over speed bumps etc, it also clears goin up an angled ramp when loading onto trucks...Where did you order it from, and does it make the center very low? I.e. do I need to be worried when going off a curb or something?
It may be possible to change the oil without removing the muffler but for me it's much easier to just remove the one bolt and spring and pull the muffler of the header. Takes an extra 2 minutes and gives me the chance to give the muffler a thorough clean while the oil drains...How is an oil change with this exhaust? Does it get in the way?
MIne just shipped today, will post..Can some one provide some basic header dimension for the Yam pipe? Inlet inside-diameter, then pipe diameter and lengths, and the location of any step-ups in size. I'd like to see how well it matches the profile generated to match my engine. Other wise I might have to get a custom header made, but this one looks sooooo tasty!
