The weight is around the same as the stock exhaust and many of the other stainless steel exhausts (Remus, Eisenmann).

There is no real drone in the quiet setting.

There is drone on the louder setting under 3000 rpm on partial load. Above... none.

The development car with this exhaust has been driven on the Autobahns already at different rpm's constantly. We wanted to see legally what the sound would be like for long crusing at 4000-6000rpm in 7th gear (not legal in the UK to do those speeds!). There was minimal on either setting.

Get on the power and the louder setting really does sound amazing.
