Is it permissible to mount a sports exhaust from a Yamaha YZF-R 125 RE06 (2008-2013) on a YZF-R 125 RE11 (2014-2016)?

Example: https://www.radicalracing.de/auspuffanlage-leo-vince-sbk-black-line-yamaha-yzf-r-125-bj-08-13 Would it be legal to mount this exhaust on my RE11, even though it's designed for an RE06? They both meet the EURO 3 standard and are almost identical. thanks in advance
