so one of myfriends picked up a passanger seat for his crx. it looks like its a seat off a crx si or a ef si but but it dosent have the hole in the headrest. im curious to find out where this seat came from. dont have a pic now but might get one later.

 

Take a try at searching on Google for images of various cars.
Not all Hondas have a hole in the headrest.
Non-Si CRX seats for sure don't have the hole.

 

my guess is that the seats are non Si......they are much more plain and less supportive, with no hole in headrest either
