You'll need to purchase 2 servo buddy modules, one per exhaust system..I have two choices at Rev Zilla for servo buddies?
I like the first pic but the date doesn't include 2023.
The choice in the second pic mean more zip ties. Any advice?
The first pic suggests they come in pairs. The second pic suggest I buy two of them?

Depends on your location emission testing... If your states side, I highly doubt it will fail... our bikes (well technically yours since I just sold mine) have wide band oxygen sensors that will tell the ecu to adjust for the exhaust flowWill you pass emission test doing the servomotor ectomy?
The exhaust valve will be permanently open basically?
Paolo, no emission test in KS.Will you pass emission test doing the servomotor ectomy?
The exhaust valve will be permanently open basically?
I did not noticed any change in performance (mine are removed) ... just a little more growling in idle and in low speeds ... no changes in throttle response or performance ... from what I can tell (seat of my pants, not dyno data)I thought it did more than just baffle sound. I thought it provided a slight, extra back pressure for smoother running and better response at lower rpm’s?
... same, something to appease the authorities in Europe and CaliWithout knowing the details, I saw the exhaust flappers as overkill.
