No. there is only packing in the silencer, if you experience problems with your ATV Or motorcycle in the region of it not going as fast as it can just take the silencer off and see if it will go faster i have had the same problem with my Yamaha Blaster i just took it off and it improved 100% but do not leave it off either buy a new one or get it repaired bc if you leave it off it WILL effect your piston by blowing it up in most cases. If you have anymore questions send me a question.
There is no "white stuff" in a silencer/muffler, unless you mean fiberglass packing. It has no use when removed.
I have an after market FMF pipe and silencer on mine.
with a viza
it's steel pipe without any processing and packing.
A 7.3 powerstroke's stock Garret turbo does not have a silencer ring inside the turbo housing.
it is called a silencer which makes the exhaust less noisier

If your Glasspack is a tip and it has a silencer in it, take it out You'll get more flow too. If it is just an inline one replace it with a one with less fiberglass packing (cheaper ones tend to have less fiberglass packing) or just removing the glasspack all together and go straight pipe. Glasspacks also get louder as they wear out. Get your glasspack hot and spray it with cold water. On the outside.
To replace the rear silencer on a Fiesta MK6, start by safely lifting the car and securing it on jack stands. Remove the old silencer by unbolting it from the exhaust pipe and any hangers using a socket set and possibly a penetrating oil to ease rusted bolts. Position the new silencer in place, ensuring it aligns with the exhaust system and reattach it to the hangers and pipe. Finally, double-check all connections and lower the vehicle before starting the engine to test for leaks.
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.
You can remove the baffles from inside the muffler but the neighbors won't be happy.
Pipe bore is the actual minimum inside diameter of a pipe, which is not necessarily the nominal pipe size.
