My CAV will be going through the SVA test in February. One of the tests will be to measure exhaust noise level at 3/4 maximum power rpm,which works out to be about 3500-4000rpm for my engine. I have a 400 fhp ford 302 and CAV headers,muffler and tailpipes.
Am I likely to pass the noise limit of 101db? Is it wise to quieten the exhaust using super-traps before the test?
