- Looking to learn the scientific way to quieten a motorcycle exhaust baffle
Hi everyone.
I don't have much knowledge in physics but I am trying to take a scientific approach to silencing my motorcycle exhaust.
The muffler is a basically a perforated straight-through tube with fiberglass packing (too loud).
The baffle (only knocks one decibel off) came as just an insert that makes the gas flow around it, never through it, and has two small bulges which i assume are to speed up/slow down the flow to disturb the sound. Not very effective.
I have drilled some holes in preparation for filling the baffle with fiberglass. The plan was to drill along the entire length but for performance reasons id now like to improve the flow a bit too if possible.
Is it possible to modify this baffle to increase its effectiveness without using fiberglass (just holes to manipulate the gas flow)
Im keen the learn the physics of how all this works as i also have an issue with the pulses not being timed correctly to enhance efficiency but that's a job for another day!
Any pointers/advice is much appreciated
