My bike, my exhaust. Not a scalvini, but a special made exhaust for my bike. Not finished yet, right side has to be done also. This is just the beginning.

wow you are hauling ass on this project! that is impressive.
i'm wanting to do the EXACT same thing.
couple questions:
- what software did you use to plot the expansion chambers?
- cut the sheet metal out by hand or laser jet?
- how did you roll them? slip roll?
- tack the whole thing up, then purge the inside and weld completely or weld each slice fully at a time?

looking at this picture again and just gotta say that whoever fitted and welded that knows what they are doing. thats some seriously tight fitment. i've looked at dozens of cone pipes and that one looks top notch.

Software is Bimotion, and everything is handmade, no laser cutting, so no dxf files.

Bimotion likes the kx500. do you have Bimotion_2-Stroke_Case_Study?
Have it on pdf

I "use" http://buildandclick.com/html/tuned_pipe.html they have dualpower, sounds intresting.

Have you use a steel wire with cardboard ring to model the route of the exhaust?
Any fancy material used and how did you weldid it?
