Your turn Brian =)

I'll leave the pipe building to the pipe building professionals. But I do admire the passion that went into this stainless pipe.
 
On another forum (atvdragracers.com), I remember reading a thread about 2 stroke pipe design. A few members there were showing some of their home made drag pipes & left commentary on how each performed on the dyno. I always give props to those that wish to take on this endeavor. However, this brings up an interesting question... What materials lend themselves to making good useable power in a 2 stroke engine?
