2-11 Exhaust silencer - Track Limit 95DB
Hello good people.
Any idea on how to lower the noise from the exhaust, most tracks in Sweden & Denmark have a limit on 95db (for some boring reason, don't ask why.)
The problem is when driving at 6000+ RPM the car is around 110-120db and we are being giving the black flag
At the moment we have in most cases resolved this by adding a small 90° pipe to point the sound away from the tracks microphone.
Does an exhaust muffler like this one help?

Any suggest that can help us without costing on performances or risking to damage the engine are most welcome
