Yamaha Sidewinder Exhaust Decibel Test 

i wonder what his neighbours thoughts.. WTF IS HE DOING??

Nice test, Beerman on TY! The one thing I noticed the last one is done on a different day with leaves down and more wind.

Nice job on the test. How’d you get all the different types to run your testing?

I noticed a typo in the video - the TD Stock Mod muffler @ 50' @ 5000 rpm was actually 79.4 db in the test, NOT 73.2 db as the video says.

Good , but needs to be done in the winter with winter temps and snow on ground for real life results ,also sit on sled when throttled up without the legs in the way . Really makes a difference . But this gives a real close number anyway .

This video is wel made Congratulation

Be nice to know the price difference between them

What's the point???? To much time on his hands.
