Greetings,
Before I put the silent insert into my 09’s Akrapovic carbon fiber hexagonal silencer, I decided just for fun to run a completely un-scientific sound check. I set the sound meter as shown in the picture about level with the outlet. Tested in the garage and came out with the following:
Without Insert: Idle – 84 dBA, 3500 rpm – 90 dBA, and 7000 rpm – 100 dBA
With insert: Idle – 81 dBA, 3500 rpm – 88 dBA, and 7000 rpm – 99 dBA
What does this really mean? I was bored and it was raining outside. No, that’s only part of it. It is a little bit quieter, but still has the same rumble (frequency).
Next time it is nice weather in MO, I will get a chance to try and compare the feel of the power with and without the insert. Maybe I can also get a drive by video with sound at the same time. I’m hoping that it will be above freezing by sometime in May.
Cheers,
MrHix
