Rumble Pack warranty

[Cheynespub]

While stretching my sled out I noticed that my rumble pack silencer was rattling. It looks like a piece has come free inside. It wont come out because its larger than the openings. Does anyone know how to get a warranty replacement for these?

It came on my sled so I dont have receipt or anything.

Thanks

Does anyone have any idea how to get a replacement can? Without buying it?
