I repacked my exhaust today and look what I found. It looks like a previous owner thought the slip ons were too loud and performed a reverse bafflectomy on them. Needless to say they came right out.

 

How big is the difference in noise ?
What are the dimensions ?
What are you going to do with them ?
I've been looking for something to install in my midpipe on my CB-1.5 to make it a bit quieter.

 

Reminds me of when I bought a pipe for my old GPz, it was almost free as the previous owner had managed to somehow drop a drill bit into it and it rattled at certain revs. I paid the money, turned it upside down and the bit fell to the floor, just before the sellers chin!
He said "I have been trying to do that for months"

 

They are 2-1/8" diameter by about 12" long. They didn't seem to make much difference at idle but the bike is a lot louder at higher rpm now. I used to hear mostly wind and engine noise while riding now it's all exhaust. I don't have any plans to use them but they are just homemade things made of welded aluminium I mangled the end of one a little trying to pull it out without removing the end cap.

 

Total cost, how much to ship to 90815 ?

 

I was just going to throw them out. I don't think they are rally what you are looking for and they broken and messed up but, if you really want them a flat rate USPS box is $10.95
