  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

3 stores FAIL for telling me that yes they stock stainless steel wool and instead it is normal steel and looks like it is quite fine even though it says "course"
 
Couldn't you buy some metal sheet mesh like they use under brick or stone on house walls. I don't know what the stuff is called, but you could wrap that between the two outlets from end cap to the reducer or whatever that thing is. Use some safety wire every few inches and then wrap the stainless wool over that. Probably worth safety wiring the wool as well.
 
I actually was just looking at some bondo mesh backing and was thinking something similar, I need something stiffer though, that stuff might work. I cant find stainless wool anywhere, this town is nuts, I have 4 "super center" type hardware stores and not one of them has even HEARD of stainless steel wool...

My scrubby pads look brand new still, true I only rode about 10km but still it is shiny as the pix still...

Maybe I will just hunt for those.

I will "steel" your mesh idea though thanks!

Try asking for bronze wool. It doesnt rust either.

For anyone who cares, it has been 3-4 days with the stainless steel "pot scubbers" and the look the same, I have put about 50km on it (I know but my ride to work is only 10k) and ridden as hard as I could.

They have black on them but it rubs off, still shiny as new underneath.

The ones I ended up getting after I ran out of the above are "Hero" brand from Canadian Tire, $2 for a pack of 3. Like my pictures above they are spiral wound so they can be stretched over the baffle and left there with no tie wraps, just keep stuffing them on there until you have the amount you want. I used 7 on mine, so $6 and 2 spares to wash pans with, ha ha.

I will repost when I have a few 100 kms on it.

It has taken almost ALL the buzziness out, and i think I may actually pull a few out as I almost liked it better with the three lumps in the pic above than with it stuffed full. :p

Not sure if anyone beleives/cares, but a cheap alternative to stainless wool (about 30-40 bux a pound from what I found) IF you can find it.

The normal steel wool looks like it may be cheaper, and obviously works as per the post about it on here. But hey we are comparing $4 to $6 here :D
 
I haven't tried it. But it would make sense to me that the finer wool would absorb more sound waves. The scrub pad is probably fairly coarse in comparison to the stuff on ebay.

Also I would load up the ends of the tubes, but not between/center of the tube. You restrict the flow by having the wool between the two ports and probably don't cut much noise out. Pack alot on each end and it will cancel out more sound.

Just my 2 cents. I am not a sound engineer.
 
I had thought about that, packing it in really didnt seem to lower the sound much compared to how much more wool is in there.

I was going to expirapent with a peice of steam pipe insulation (pipe shaped) I grabbed from the trash at work too, high temp and shaped like a tube, plus its compressed already, thought that might work in the middle and leave lots of room for the exhaust to flow by leaving the center/middle open... who knows, just playin now... :)

no, see the pictures, they are not sos pads.
 
ok so I took out all the stainless packing except for at the ends, and then wrapped a peice of steam pipe insulation (pre formed in a cylinder, compressed to hold its shape) around the middle part. Bike seems to ride MUCH better.

I will take pics, and most likely expirament a bit with the fiberglass thickness and shape but I think I found a happy medium between sound and restriction. Still plan on finding a new can for this system, the rest fts nicely, but man does it sound like crap out of the box...

thanks for the suggestions guys!
