years ago the Eltham Dirt Bike Centre used to have a lot of stuff for the DT's, I thought they had a pipe for the dt's or they may have used bassani or Pascoe of the time. Geoff Morris will whip one up for you. im sure it will liven the old girl up.

I gave him a call today..seems like a really nice fella we had a good  hat but due to the fact im in newcastle nsw he cant help me as he would need the bike to build the pipe..I would think a yz or IT pipe  may be good start of similar vintage

you should be able to buy an old dt 400 in Victoria, give it to Geoff as a model, then flog it when he is done! ;D

probably cost the same as a day trip to victoria ;D

Geoff made me a YZ 400 pipe that was for a MX360 frame apart for brackets the same as a DT400 twin frame , I could send it to him to copy for you . Iain

Look on evilbay USA [not OZ] and see if you can find a Bassani pipe for it, I had one back in the day. There will be others too....maybe Torque Engineering?

One of the differences I think would be the YZ / MX would have the usual slip spigot join with springs and the DT would have a flange mount system?
