Non resonated non baffled with sports Cat, DOES drone for the first 200 miles or so, then the tone changes. At 4-500 miles around town is silent. At 80 it's silent. Put your foot down in any gear or any revs and it barks like a mofo.
People 100 yards up the road look back instantly or 'just as you are going by'...they know a tasty machine is heading towards them
