Hi guys I've got a 420R on order which should be mine in July. Ive been wondering what other 420 owners have experienced with regards to trackday noise test results. Donnington being my nearest track usually has a 98 decibel limit. Whilst I've specked the car with the track day exhaust, I know 620,s with this exhaust have been over the limit although the 620 is a different beast. Thanks in advance, Jason
