The build quality of this exhaust system is excellent, top-notch materials, precise fitment, and it includes everything needed for installation. One thing they don’t mention is that it fits MQB platform vehicles (Audi Q3 S-Line Premium Plus perfect fit). However, a major issue that’s not being mentioned anywhere is the extreme loudness when paired with a 3" downpipe and high-flow cat.

The tone is exceptional, deep and aggressive, but the volume is excessive, track-car level loud. I reached out to customer support hoping for advice or potential solutions, but unfortunately received no real help. When I asked if they were aware of how loud it is, the support rep didn’t seem surprised, which was disappointing.

I ended up adding a resonator, and it's still far louder than expected. What’s frustrating is that there’s no clear disclaimer or warning about the sound levels. In the past, systems with just a few dB over stock used to be marked as “track only” or “off-road use.” That kind of transparency would’ve been appreciated here.

In summary: Excellent product quality, but be prepared for a very loud exhaust. Don’t expect much in terms of support if it’s too much for your needs.
