The following is an email written by "Dorian Sleeper"
to Novation Racing. It outlines the procedure and
results of a sound test that Dorian conducted with a
Novation Racing silencer on his 500cc Matchless
Metisse. Dorian's concern to quiet his beast was born
out of Hollister ORV Parks 99dba sound limit
restriction being applied to vintage race bikes and its
impact on future vintage racing events and venues.

Thank you Dorian for your time, effort and professional
approach in performing this test.
