I don’t have an Exeo but as said above if no other modifications are made a normal paper filter will make the same power as a ‘performance’ filter.
Turbo diesels suck in a large amount of air and compresses it first in the turbo then inside the cylinder. A small amount of fuel is sprayed in and you have a power stroke. Most road diesels run lean on fuel and there’s unused oxygen in the power stroke. So the amount of fuel injected will be limiting performance not the amount of air sucked in. This is why they respond so well to remapping, more fuel is injected to burn the unused oxygen. If too much fuel is used you’ll get un-burnt diesel out of the exhaust as black smoke. Then the turbo boost is increased to put more air into the engine, you’ll need to be running very high boost levels to find the normal paper filter a restriction.
It’s a personal choice but you’re highly unlikely to get the performance increase that the filter manufacture is claiming.
