b.weeks Posted February 28, 2008 Share Posted February 28, 2008 You should be fine for there. I think I recall I had a standard dB reading of about 89dB when I went to Bedofrd and the limit was 91dB. Forget what the drive by limit was now. Link to comment Share on other sites More sharing options...

SUPRASUZUKI Posted February 28, 2008 Share Posted February 28, 2008 Noise tested at Cadwell, Kakimoto cat back (no baffle fitted), double decat, 98db against a limit of 105. Edit:- Static test, carried out by their own people, so ligitimate (not carried out by me!!). HTH Link to comment Share on other sites More sharing options...
