Hi Merlin
the QD weights about the same as my Standard headers with the Akrapovic can but not weighed them.
Baffle is fitted in shots and uncorked was 108db on snetterton noise meter.
lost all the top end with baffle fitted but still great fun.
A lot of people like the exhaust and a few hate it (Marmite pipe?)
Rick
great fun was had by all (mate on Husqvarna Nuda 900 was with me)
