tri color gets full system,not slip on's, which is what would have been fitted, hence that extra power etc
In fact I supposed the same... but he himself in that article speaks about slips on only ... maybe in not all the countries Tri is with full sistem on ?
In the other post where that guy shows his Tricolore at the dealer's.... the bike has the stock cans on ...
I know some of the newer bikes like the zx10r already have fairly large diameter headers. Therefor, you don't really get all that much with a full system vs just the slip ons. Not sure if the new duc is the same way?
My dealer just installed my Full Termi syatem - seen it today. They stated the Stock measured at 60mm and the Termi headers measured at 70mm. They measured twice as the Termi headers looks much bigger on the bike than the Termi 70mm headers on the 1198.

My understanding is that the valve is in the manifold section. Valves in the exhaust are there for sound, they will not make any significance to maximum power, yes there will be a small restriction with them in there but it would be less than 1bhp. Changing the manifolds will increase power but it will be from the pipes themselves not the valves that may it may not be in it
That would depend under what criteria Ducati's ECU is set to close the exhaust valve. As we've speculated on other threads and suggested by yourself, if the main purpose of the exhaust valve it to meet noise regulations, which will sap power when in its closed/restrictive position, why wold anyone want to keep it?
I've heard many reports like "I was traveling at x speed in y gear and everything went quiet. When I twisted the throttle, the engine bogged for a sec then the noise and thrust returned".
With the exhaust valve in its "closed" position, the engine will run rich, to which the ECU will cut back on fuel to compensate.
I merely stated that it would be good if the slipons included a link pipe to remove the exhaust valve, not that replacing it was going to give increase in power. Well, except during those times when the ECU would normally tell the valve to close.
don't get me wrong i think that any valve in the exhaust is wrong (thats why i will always put a full system on any of my bikes) Their function is there to please the mamby pamby rules
