Seen a couple of videos where people have wrapped steel wool around the baffle before wrapping with packing material when packing 4 strokes, is this recomended?

From what i gather it helps keep the heat away from the packing material and also stops it being sucked into the baffle and blown out the back thus extending its life and the reason manufactures don't use it is partly cost and partly because of the revenue of packing kits. Worth trying?

i was thinking rust would be a killer. if you had moisture or condensation, your gonna get a hell of a lot of rust juice all over the place. fiberglass packing does not rust, corrode or break down. but using only a small amount like they do, should be ok. i would like to see how it looks after a season.

Good point, stainless steel wool should be ok. Although the heat from the exhaust should get rid of any moisture build up.

I'll never understand why anyone (including the manufacturers) would put a flammable material inside a silencer.

Wrapped tightly it 'shouldn't' be a problem.

Moose universal packing kit comes with stainless steel mesh as the first layer of wrap.

Any thoughts on whether this could have any effect on the overall noise level of the exhaust?

Many OEMs include (and have for quite some time) steel wool around the core. Top of the line aftermarket exhaust manufacturers do the same. Spending more money now for steel wool will have a big impact on the interval between repacks. Google Moose steel wool kits.

RipGroove99-I was told (by pipe company's customer service guy) the steel wool takes about an hour to break in but after that doesn't adversely impact sound.

I made a muffler a little while back and would advise wrapping the core with stainless steel wool.

I originally wrapped mine with regular steel wool and it caught fire on the first run and spat metre long flames out the exhaust! Don't get me wrong it looked awesome but I wouldn't recommend it.

A thin layer of tightly wrapped (stainless) steel wool will not catch fire and will make the fibreglass packing last longer.

heat creates moisture buildup... condensation.

but stainless steel wool would be fine. but prob expensive.

Water is a byproduct of combustion. There is ALWAYS water present in the exhaust of an engine.
