'17 RCH Suzuki build question

I have a '17 RCH Suzuki RM-Z450 bike build that I have been working on over the last year or so and I have a question that will probably be hard to answer. In '17 they started using the Yoshimura RS-12 exhaust on the RCH race bikes but Yoshimura never sold the RS-12 for the '17 RM-Z450's. Does anyone here know how close the bends and mount points are between the '17 and '18 RM-Z450 pipes?

I appreciate any help or comparisons I can get from anyone here.
