Greetings! I've been trying to find more info on the Graves "EVO" (IIRC) 3/4 exhaust for the 2015 and up R1's. It looks nearly identical to the 3/4 de-cat link system that's currently available but it includes an Exup-style butterfly valve that connects to the original actuation cables and Exup motor. I haven't seen anything on the Graves site, and sent them an inquiry message about it but have yet to hear back. Do you have any info on it (price, availability, etc.)? Thanks for any light you can shed on this!
