^Yeah, you have to order this, it's the 'Mines Add-on Spoiler'
It took me about 2 month-ish, if I remember correctly to receive this.
But installation is REALLY simple, clean your original spoiler form grease and oil,
Attach the 3m Double-sided tape that is provided from Mines,
Align the spoiler and attach it to your OEM spoiler,
Drill in the bolts.
But if you want to get it installed by a shop, I'm pretty sure any shops in your area will be able to install it for you =)
