LEON FR 2.0 TSI 190 PS( Mj2019) Rear silencer, loss of warranty?

Hello guys, I’m looking for a rear silencer for my new lion (ULT 05. 2019). Since I have time until the one arrives I wanted to deal with the matter The original doesn’t sound sporty at all, although I chose the FR variant! So of what I saw and heard on Youtube. By the way, this is my first seat, before that I drove 3 Alfa Romeo! My question is if when I change the rear silencer my manufacturer gara ntie lose, you know what? Experiences? If not someone can recommend something to me? Since I have a 4 year old daughter it wouldn’t have to be so loud as we drive to Italy once a year, best only when riding sports it should get louder Below is an example as a screenshot… Hope you can help me.. Sincerely Daniele
