I have a 95 +8 with cast iron manifolds cats and a half metre of straight thru expansion chamber on either side (did have librands silencers till they fell to pieces internally)-sounds good and not too intrusive (regularly do 500 mile trips).
pulls all the way from 10000 rpm
I also have a 94 +8 with librands highly complicated twin exhaust -sounds very peaceful no fuss on overun etc.
only seems to come alive above 35000 rpm
