I read somewhere for the 1090rr the exhuast was reworked. The picture of the double pipes looks to be an older brutale, not sure it will even fit. Regardless, which exhaust would you go for??? I'm can't make up my mind. These systems also come with ECU's. Hope they are compatable for 1090rr. The Evolution website says so, but the pictures don't look like 1090's.
