Can also check on ebay, there is or used to be some brands offering the same straight through type nuffler for very cheap, like $70/pr depending on size. Think it was "full boar" or something like that.

Basically the same but half the weight of the Ultraflows..the Ultraflows are built heavy and last..the fiberglass packing may move around after years but they last forever.
