A4 Diffuser retrofit

[cyberstretch]

Hi there all

Does anyone know whether all A4 rear diffusers are interchangeable ?

I have an B8 SE saloon which has a pretty boring diffuser and i was hoping to just pop it out and put in a better looking one, maybe from an s-line ?

I am aware that the bumpers on the S-line are a slightly different shape but i wasnt sure if the diffusers were that same.

Any info would be really appreciated
