quite the newbie with the technicals,

but can the a45 exhaust system 2021 swap onto an a250 2019 petrol?

see pic for the a45 system, looking to purchase this (and a new diffuser to fit) onto my a250 w177

Hi.

Looking at the pic I would say that system is from an A35 due to the single exhaust outlet tips.

Unless someone here has done it before and knows for sure it fits, I would think you would need to get your car in the air and inspect the underside.

I think it will mainly be the mounting points on the chassis that could be an issue.

You will need to change the lower bumper to make way for the exhaust tips. The A250 has tips pointing downwards behind the bumper.
