Jason Plato Posted April 7, 2003 Share Posted April 7, 2003 Depends which exhaust you have - mine when standard on a 6" diameter exhaust used to make 97-99 Db . Dave Link to comment Share on other sites More sharing options...
jerrypike Posted April 7, 2003 Share Posted April 7, 2003 mr t lots of variables, probably 101-102 @ 3/4 rpm if you're thinking of goodwood98 days or castle coombe, take a good book jerry Link to comment Share on other sites More sharing options...

MikeE Posted April 8, 2003 Share Posted April 8, 2003 Had my standard (single exit pipe) tested at Goodwood and was well under the limit (apparently). Robmar - I fitted my Powerspeed 4-2-1 in January and would be interested to know the new noise level (actually I don't think it's any loader than before). So let me know if you find out soon. cheers, Mike Link to comment Share on other sites More sharing options...
robmar Posted April 8, 2003 Share Posted April 8, 2003 MikeE - yep will do, I am sure mine is louder but not by much rob Link to comment Share on other sites More sharing options...
