I’ve seen a few Exiges with horazontal slats in the front air vents either over or instead of the grilles/mesh;- where do you get them
Is that not called an elise? 
I have never seen an exige with them, most elise owners want to change their mesh for grilles.
Im presuming you just mean the 2010 MY front end? which you can get from lotus dealers only i think and is very expensive.
