BISIMOTO Headers, need advice

Really need your advice on BISIMOTO Headers, to use in a really low car,
Do they sit lower then stock headers?
For the price range they go for is it worth it?
And most important how can i tell if its fake?
I have come across a set for sale really close to my area for a good price, and i don't want to loose this chance to get them .[list][/list]
