Slowy, I had some "fun" getting my 351 C passed. It started out as a stationary test on a "temporary" system to pass rego...just kept adding mufflers. In the end it passed the stationary test. Then I was required to pass a "drive by" test. It kept failing because it "whistled" too much. It was quiet to the point that standard cars were noiser. The muffler man was stumped but I tried a larger diameter pipe and the whistle dropped in decibels.
After creative mathematics the official report met and exceeded the required decibel level. I had a good argument point after the noise test man admitted that he used to pass harley choppers for rego. Ha ha ha..good luck
