The sound is, how can I say it, LOUD! I'm so glad I went for the BCS drone delete because at least this pipe doesn't drone. The problem is the backbox, it's really loud from 2.500rpm to 3.000rpm on part throttle, like you hit the resonance frequency of the backbox. I love the res delete, I really do but with a passenger in the car (a non car lover) it can be a bit too much - but then again, do I need a non car lover in my life???
I'm now working on putting some sound insulation in the back and it have already reduced the problem a lot
I drove a 2018 RS3 and that was just boring to listen to compared to mine because it 1: had stock exhaust and 2: had the rear seats.
Actually I just broke up with my girlfriend after 6 years relationship so when all get settled with her moving out and so on I got a lot more cash to spend on the S3, that's why I'm going to get it lowered, tuned and fit some exterior parts in the spring. And yes she was a non car lover so that's why it probably didn't worked out
- she always complained about the S3 being too loud
