Motorgeek, what if a person came to somebody like you, with your experience, with an engine built with all the goodies in it that we know of...and done to it.  Could you or somebody like yourself, build a hand made pipe around that engine, and that fits without modifying the frame, or does one simply build an engine around the pipe?
 
Basically I want Carl to build my engine with all of those little things done to it.  To make as much power as possible, and I want a beautiful hand made pipe built for the motor. It can be raw, Ill get it chromed myself.  Any advice on how to get this done would be greatly appreciated. I'm feeling lost and confused cause I'm new to this.  Which comes first? ... The chicken or the egg?  I don't want a pipe that is based off 25 or 30 year old tech technology.  There must be a better pipe waiting for someone like yourself to create.
