I just ordered the ECS diffuser, too, so I’m excited to get it and put it on. I think the gloss black will look good with reflex silver. Thanks for the photos!
 So fitment on my 2016 GTI is ok. It takes a LOT of finagling to get it where it needs to be. After some swearing, though, it fits decently well. Looks great on.
possibly stupid question.. do you have to remove the exhaust?So I just installed this today.
Fitment was fine, no issues there. Very quick job, done in about an hour. Hardest part, which even gets called out in the instructions, is removing the OEM diffuser. You really have to pull to get it away from the bumper. Definitely wear safety glasses. it's amazing how much gunk gets caught underneath the car. Constantly have shit falling into you face while working.
The diffuser itself seems very thin and flimsy, so I'm curious to see how it holds up. Looks great though. If anybody knows of any matching gloss black sideskirts, let me know.
