Thailand exhaust? Ebay?

Not really sure where the right place is to ask this question, but I need some new mufflers for my 72 cb175. these Thailand mufflers keep coming up and I actually like the look of both of these, and I love the price. but I cant seem to find anybody talking about them. Have any of you guys tried these out?

here is a picture of my bike and a link to those mufflers on the ebays
