Quieting an "Ulster" Exhaust
#10
Actually it's not how loud it is but it just sounds really rattley.   I'd hoped to be able to achieve a more "rorty" sound and have heard other cars at VSCC events which do have a much deeper and more consistent sound.

If you hold the body of the Brooklands style silencer it does seem to dampen out some of the unpleasant noise so I guess it's probably resonance being amplified by the flat sides of the silencer.   

I did consider drilling a hole right through the silencer and then passing a bolt right through so that the two faces were under pressure but I'm a little reluctant to damage it in that way.   Perhaps I can somehow clamp the faces for a trial just to see what happens.

May also try removing the fish tail to see what effect that has.   Mine doesn't have the small holes drilled into the outer face of the fish tail so this may be something I can try if removing it has any effect.
