Looking good! ( i was wondering who picked those up) I love my LSE tails, yours look great on there.

P.S.
Also just a quick thought, on my last car ('15 Audi A3) I swapped the S3 exhaust onto it for sound, but it also has different tips than the A3. They are oval tips kind of like yours, but they have a slight angle and contour to the outer edge. I was looking at your rear shot and thought maybe it something you would be interested in! The stock 2015+ S3 and 2015+ Golf .:R use the same tips, and there are a ton of guys who upgrade their stock setups so my guess is they would be readily available. (I also have part #'s so you can do a OEM parts search too) Here is a pic I took before I sold mine, wish I still had them I would send them to you for nothing. Like I said, the angle might match teh rear LS bumper a bit better and look more flush. Yours do not look bad, so please dont misinterpret my post as "Hey fix your tips"
Slight idea of the angle here relative to a curved valence
