HELP! How to clean Pipe Assy

[big poppa]

Hi guys... need your suggestions and recommendations on how to properly clean a pipe arrester. Please share your opinions! Thanks.

A locally made aftermarket pipe assy was given to me by a friend and while trying to clean it its insides, I noticed that oily deposit and grime was heavily present.

Its not the regular "dried carbon-oil" usually found in pipes but rather fresh, wet oily stuff. I know that owner said his bike was running blow-by for a long time and this might have caused the build-up.

This arrester though is the riveted type and not allen bolted/screwed type like other brands, so its tricky to disassemble and clean up.

Please share you your tips and recommendations..if there is a way to clean it easily. Thanks a lot!!!

i think u should find any shop that have rivet remover its just like a plier coz with that plier u can remove and re-fit the rivet....definitely u need that to clean inside the pipe coz u need to open it....by the way what mags is that??? looks cool though

i think the best way to clean it is to open it by pulling all the rivet only then you can see the inside and can be easily clean..you can also replace the old thing inside (asbestos) is my term right? they say that they brittle on a certain period due to long usage which affects the pipes sound, muffler stores have the tools for pulling rivets and replacing it

Bro,
You just need engine degreaser, you can buy this at any auto parts shop, Spray this degreaser inside your pipe and wait for several minutes to melt the oil. then wash it with water. repeat if needed

disassemble the pipe....remove the fibers(probably they are soaked in oil too)

then avgas will do...very powerful solvent...if only i still worked on my previous company...we have a chemical bath there that removes carbon deposits...just make sure it's not aluminum...or else it will dissolve in the chemical....haha

Thanks Dude. Lets try and give some of your old friends a visit, huh? I may need some specialty shops to do it for me though as this one is Riveted and not bolted on like our hgms... JP-4 or jet a-1?? hehehe we got drum loads here...

Sir, The best way is to drill or pry out the rivets, remove the baffles, soak it and the arrester in kerosene (cheap), use a small steel brush to remove caked oil deposits. Better if you can find brass instead of steel to avoid excessive scraping on the aluminum arrester and replace the fiber pack with a new one. It only costs 100 pesos here in Marikina. the repacking and riveting. For the pipe, I used "plehe". The one used in removing clogged dirts in kitchen sinks. Or u may use a thin flexible flat steel to scrape out the carbon deposits. This is my own procedure done on the pipe of my previous bike. HTH!

sounds good sir.. thanks! just need to get a shop to do the disassembly though as any leaks or sippage might cause improper operation right? thanks

Update:

Thanks to all who responded...

I drilled out the rivets, pulled out the metal screen inside and the soiled fiber. then I just cleaned all the metal parts with carb cleaner and soap, then bought new fiber materials. USD 2 worth of fiber is good enough for at least three (3) mufflers so I just put in generously and closed it up with new rivets plus sealant and voila! a "semi-new" arrester... just need to have it buffed though Thanks again everyone!

That is good news sir! Noticed the change in sound and performance? Just check the places where leaks may occur. It will cause backfiring.

Yeah kinda muffled at low rpms and blows out in the mid to higher ranges.. need to R&R the rivets though as i used construction quality ones and some of them were not in the proper length and may a bit loose. I will try to replace them with acft grade stainless cherry maxes

To TS.. as addendum to my drawing before, I opened another brand's muffler and basically the same principle except for the inner tube:
