I did the testing on the EVO Magnum Muffler with Wi. DNR and the EVO Magnum muffler passed the decibel test.

TD Super quiet is very quiet. Heck people think the TF is not loud and to me it's loud compared to the SQ.
If you want quieter a TD stock modified muffler is the next step. Any straight through muffler will have more low frequencies than a baffled/chamber type muffler like the stocker.

thanks for the reply.

If this question was for me....here is the DNR form. 2 tests and the average came out to be 87.35 decibels, 2,500 rpm at 13.1 ft. which is legal for the 4 strokes.
