It could just be that you are burning out the packing inside the muffler, a flapping sound after a quick push on the accelerator probably means that the packing is already gone. could also be an indication of poor ignition on that side of the engine.
Start your engine and look at the exhaust. If there is a lot of white smoke coming out, you have water in your gas. You can also place an empty cup in the stream of the exhaust. If water droplets appear in the glass, you have water in your gas.
the light rays hit the piece of glass and the surface of the glass causes it to refract
Sure.
The Glass fibres are the sound absorbing material that the exhaust's silencers are packed with. Eventually the internal structure of the silencers rusts away, allowing the fibres to come out the tail-pipe. The exhaust system needs replacing.
Glass pack muffler is a term used to describe a muffler configuration that uses a "pack" or lining made of fiberglass strands to reduce and dampen exhaust noise. The "glass" cannot be "broken" like a pane of glass. Over a period of time the individual strands will deteriorate due to thermal expansion/contraction, harsh exhaust corrosive gases, and road shock. This will lead to a louder exhaust note but reduced back pressure.
Are the best exhaust ever, yes. .... flowmaster pipes, glass pack or cherry bombs and no cat converter..... or no exhaust at all... less torque but more HP
Yes
The light waves coming from the pencil change speed when they move from air (faster speed) to the glass or water (slower speed). This change in speed causes the light waves to refract or bend.
Glass does cause disperssion. Think of a prism.
Yes, you can. But its pointless because a glssspack is a muffler. Just have a glasspack installed. Or a full catback glasspack exhaust system installed
Glass
Seeded Glass has pinhead sized bubbles. The glass softens the light coming from the bulb inside and replicates the naturally seeded glass made in colonial times.
