Thruxton noise limits for Cerbera

[raspberry]

Has anyone driven a Cerbera 4.5 at Thruxton? Did a standard exhaust get past the noise limit test?

[B19TOY]

Yes B19TOY went around in 1998 and 1999 in standard trim with cats. Another 4.5 was black flagged for noise however. I will not pass now - older exhaust = louder exhaust. I test at 105db @ 0.5 metres static. Supertrapps ( courtesy of Demon Tweeks and many beer tokens ) keep B19 TOY quiet enough for a Goodwood quiet day.
