TÜV combine different input range silencers

Moin, who can tell me if something like this is allowed? So not only somehow but 100%. ESD of the company A with EC permission and VSD of the company B with ABE. Everywhere this is discussed, I can read out nothing definite, because it is simply mounted. Just as naturally as Erzaz tubes etc… I would say it is not allowed. For my model there is only the rear silencer of Roar. I could send an original to Spain via the dealer. I don’t know the price yet. As they can create a template with it, there should be a discount in it. In case of an emergency, if the price is not too exorbitantly high, I’ll do it. If it’s allowed, I’ll spend a little bit more. Thank you…
