What does exhaust packing do? The purpose of exhaust packing is to absorb as much of the sound waves coming from the combustion of the engine as possible. The softness allows the sound waves to dissipate between the fibers of the packing.
What can you use for exhaust packing? Stainless steel wool works really well, too.
I’ve used regular steel wool in a pinch and it’ll get a season or two before it rusts and blows out.
With either type unwrap the pad and then wrap the layer around the core.
The trick to either steel wool or fiberglass is to over-wrap it with enough safety wire.
Does exhaust packing expand? The material expands when the exhaust heats up, textured yarns not only fill mufflers with highly sound absorbent, high heat resistant material but the revolutionary construction of the material ensures the mufflers are filled to their maximum capacity.
Does exhaust packing affect jetting? No a temp change does not change your jetting, it is a change in temperature. Altitude does not change your jetting, it is a change in Altitude.

Will no muffler hurt my engine?
If so, then most likely your cars performance will be worse than it is with a muffler because the back-pressure the muffler creates helps give you more low-end power.
You are not going to damage the engine or internals or anything without having the muffler.
no it doesn’t cause damage to the car.
Can you run a 2 stroke without a silencer?
2-strokes run fine without mufflers, if your muffler pipe is an expansion chamber you might notice a low to medium power loss, but you should be fine.
Without the muffler, the bike will probably run lean.
Too lean and all sorts of serious damage can result.
Can you put steel wool in a muffler?
It was a good trick to pack the bored out mufflers with steel wool to get to quiet noisy exhausts. Mufflers packed with stainless steel wool will last up to 4 to 5 times longer than by using fiberglass alone.
Can you use house insulation for exhaust packing?

Can you over pack a muffler?
fresh muffler packing can produce an almost two horsepower gain (from 7000 to 8000 IPI) over a worn-out muf- fler.
A blown muffler will also cause a drastic loss of low-end response.
place to lose packing is where the muffler can- ister meets the mid-pipe.
Does exhaust packing make a difference?
It’s also easy to just plain ignore it, but you will be reminded by the effects of blown out exhaust packing every time you ride your dirt bike. Your bike will not only be louder (not in a good way), but you will also lose low end torque and overall horsepower from blown out exhaust packing.
Does muffler packing affect performance?
It’s also easy to just plain ignore it, but you will be reminded by the effects of blown out exhaust packing every time you ride your dirt bike. Your bike will not only be louder (not in a good way), but you will also lose low end torque and overall horsepower from blown out exhaust packing.
What is exhaust packing made of?
The packing, which is almost exclusively woven fiberglass, gets matted down in that junk, and often compresses to the point where exhaust gases slip right by it, rather than traveling through the packing material.
What does a silencer do on a dirt bike?
The 2-stroke muffler (or silencer) sticks out the back and releases the exhaust.
(As if you didn’t know that.

A muffler delete system (or simply the process of removing the muffler/mufflers) will make the vehicle sportier to drive courtesy of the louder exhaust sound.
Does removing muffler add horsepower?
As a rule; the quieter an exhaust system is, the more horsepower it is stealing from your engine. Removal of all mufflers and resonators will provide slightly greater increases but remember as the restrictions are removed the exhaust grows louder.
Why are 2 strokes so loud?
The main reason that two stroke engines are loud is that they fire twice as often as four stroke engines. Two stroke engines have a very extensively designed exhaust system (expansion chamber) that reflects the sound wave back to the cylinder at a specific time.
Do FMF pipes add power?
FMF Factory 4.1 System
Why are 2 stroke exhausts big?
That bulge is called an expansion chamber, and it is used to increase the horsepower of the engine (see this page for a photo).
This technique only works on two-stroke engines, which is why you see it on a lot of dirt bikes but not on street bikes.
Is steel wool heat resistant?
During the production of steel wool, a slicing tool shaves fine threads of metal, which produces a tremendous amount of heat.
Keep steel wool away from open flames and any kind of electrical or mechanical spark — unless you want to start a fire.
Can you use 4 stroke muffler packing in a 2 stroke?
2 stroke mufflers are NOT meant for 4 Strokes. will it work yes. but there are different packing’s for 2 and 4 stroke. If you do put this thing on a 4 stroke please repack it with the 4 stroke packing. you will start a fire if you don’t.
How hot does a 2 stroke silencer get?
_j0kA_ “On a two-stroke the header section of the pipe can run as high as 1500F in some cases, and the rear convergent cone before the stinger can run even hotter, but normal running temps will tend to be a few hundred degrees cooler.
Will repacking a muffler make it quieter?
you can pack/repack the exhaust but it won’t be that much quieter because the end can does not contain that much volume as compared to the larger stock exhaust can. you need more volume to absorb sound waves or separate chambers for sound waves to cancel out.
Is there fiberglass in mufflers?
It’s probably fiberglass, or some such thing. It’s used to keep the baffles in the muffler from rattling when the muffler starts to get old and the parts loosen up.
What is inside a motorcycle muffler?
