b8.5 s-line rear valence

[MrRanger]

im looking for a rear valance/diffuser that will work for a facelift a4 with s-line package that supports dual exit singe tip.(similar to the avant style) the exhaust in question can be seen in the link https://www.ecstuning.com/b-ecs-parts/audi-b8-a4-20t-dual-exit-valved-exhaust-system-turbo-back-or-cat-back/003353ecs02~dk/?pdk=AAAAAAAAAAAAAQEAAAMDAgQC.

Thanks for any help.

So this is a sedan? OE spoiler would be p/n 8K0807521K, with either color code 1RR (platinum gray) or Y9B (brilliant black). And then the trim piece that goes in it is 8K0807833B, with color code 01C (satin black).
