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?

It's not so much an advantage, it's just different. Let's say for example it shifts the torque curve 300 rpm up. Which drops peak torque 5 ft lbs. Changing the tuned length to shift the toque curve back down 300 rpm should gain most all of the torque back. I'm betting the percentage of difference after the tuning changes are made would be insignificant.

The major down side is that it could take building several pipes to get the differences ironed out.

I am no expert of two stroke pipe building by any means, so take this with a grain of salt. Jerry is one of the best 2 stroke guys in the business from what I know. I talked to him quite a bit about this when I had him build my hybrid pipe, and this is what I gathered from the conversation. I have also gathered this from what reading I have done. And I'm in NO WAY trying to put words in anyone's mouth, or proclaim to be an expert.

But because of my research and conversations with Jerry I did make a few small changes to attempt to compensate for the differences. I doubt I accounted for everything on my first ever attempt, but I've had a lot of fun.
