We measured the dB with the vampire exhaust.
We did a 'referentie-meting' as we call it in The Netherlands.
( measure about 50 cm in an angle behind the exhaust at a sertain RPM. )
The vampire made 91,5 dB. It's a bit to loud, but because I get an
exhaust which is 5 cm longer,
my exhaust will be a little bit more silent.
The future was about 87 dB.
The orriginal exhaust about 81/82 dB.
Greetings from The Netherlands,
Raymond Fels.
