Hi, I'm looking for some advice on my A3 Saloon. I have a new 2017 facelifted A3 saloon and I'm looking to put the S3 facelift diffuser on my car so I can put a new quad exhaust on it, however the only ones I can find have come off a facelifted sportback/hatchback not off the Saloon and I'm wondering if the fitment will be the same or different? If anyone has any ideas I would really appreciate it, Thanks
