AHH HELP, installed MAC 2-1 and it falls on its face, running out of time!

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.

You're not using "SOS" pads are you?

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!
