From memory purchased from Ducati its about 2.5 K
CF slip ons open air box with K & N washable filter and ECU.
Delivers more power and a cooler running engine , oh and it sounds a bit better
You could shop around get some cheaper cans , cut the box yourself and check at Houston superbikes in the US for a cheaper
ECU as an example Ducati quoted me $1800 for a DP race ECU for my S2R .......delivered from Houston $460 .
Then spend $100 at D-Moto for a tune balance the throttle bodies O2 balance and TPS reset .
