I own a couple of Goldies a DB32 350 Clubman bored out to 400cc and a DBD34 500 clubman.
The 500 really barks out like you would expect it to do. Sometimes it is embarrasingly loud when travelling through built up areas.
The 400 is very quiet compared to the 500 which uses the same pipe and silencer.
Even when i remove the straight through "goldie" silencer, there is hardly any difference in the noise volume, in fact it has a very wooly sound compared to the 500. it sounds like the pipe has cotton wool suffed up it.
Has anyone any ideas why it is this quiet?
