Yamagodden Posted February 15, 2020 Share Posted February 15, 2020 Is this standard size pipe into the silencer box? Quote Link to comment Share on other sites More sharing options...
feetupfun Posted February 15, 2020 Share Posted February 15, 2020 The diameter is as close to standard as you can get when using pre-formed exhaust pipe bends. The vertical run has been shortened from standard to get the pipe closer to the head to provide clearance for the underside of the fuel tank.

I can see how its shortened as you have described Yes the top bend is made from a pre-formed exhaust pipe bend. They come in various diameters and one size is smaller than TY250 and the next size up is slightly bigger than TY250 Quote Link to comment Share on other sites More sharing options...
