nc30 differences between a half-system and a full-system?

[porndoguk]

-The internal diameter is smaller
-any welds, breaks, joins etc will cause pits for gasses to swell and slow the smooth exit
-the rear manifold is far more twisted again causing more restriction to a smooth exit

There is about 3-5hp lost in that there manifold when compared to say a full tyga system
I had a yamamita half system with a tyga 330mm can, i ran 55hp with a few carb niggles, youve not been here long but i have some wierd carbs ask anyone!

Fitted the tyga system and got 61hp nlbut with still carb issues now theyve been ironed out and i plan on another dyno run at some point to see a clean curve and maybe a few more ponies.
