Steel wool in your exhaust

[yankee99]

I noticed lots of bikers shoving steel wool in their exhausts at the entrance to khao yai national park.  They all passed the sound check.  Has anyone tried this?

People used to do that on their 4-1 systems in the 80's when police with decibel meters became more common and it works just fine

i use it as temporary baffle sometimes ......muffles the sound very nicely

Actually it is permanent and actually gets quieter as the soot builds up, easy cheap fix though a bit unscientific/inefficient.

 

You can clean your pans with it too and the soot absorbs the grease too.........

Really i was under the impression it burns away and at night small pieces of glowing steel wool come out of the pipe.

When I bought my Honda NV400 that had wire-wool in the silencer, looked as though it had been there a long time. It was greasy and sooty, but the wire gauge was coarser than a standard brillo-pad and the box was quite a long way from the cylinder.   

 

Yes, the wire wool was more like swarf, so unlikely to burn under those temperatures, the box was stuffed with rock-wool afterwards.
