That's fine its no big deal. You don't need to a prick about its only a pipe. Christ you act like someone is trying to bang your old lady.
 

I didn't really think I was being a prick....I guess offering to help by posting up info on how to layout a cone is being a prick nowadays? All I was getting at is if you can't plug the numbers into these equations and solve for everything you need, then I'm not going to type out a big old math lesson. There are sights on the internet that can do a far better job than I can.

Also, I'm not giving out pipe dimensions. If I give out critical dimensions off of an HPR19 or Q pipe or any pipe for that matter, that is unethical. I'm not going to do that. I am not a pipe designer either, so I can't design a pipe for you and give you that info. I understand not wanting to shell out big bucks for a pipe, and the appeal of making your own. I have been there, but you are going to have to either design your own pipe, or buy one, or find someone else to give you the info. There are books out there that cover two stroke pipe tuning. I found a free copy of one on the internet once upon a time. It was very thorough, and made pretty good sense. I'm betting if you put your mind to it you could design a decent pipe with it.

Anyways I do appologize if I came across as a prick. I was tired and didn't feel like typing enough to thoroughly explain last night. I also needed to draw this diagram out to show how this worked.
