Take it to the Muffler man at Kingswood. He will do it and issue a certificate.
Costs $80 from memory for a test with certificate. I think you do have to book with him but.

according to my engineer cert its measured at 1550 mm at a 45 deg angle directly behind the exhaust..
the legal limit is 90 db. the tests are measured.. 4 cyl= @4000rpm 6 cyl= @3200rpm v8 = @3300rpm and rotory =@4500rpm |
