$3 DIY DIFFUSER with a CHOPPING BOARD! (seriously)

After upgrading my exhaust, I wanted a rear diffuser for the car to match the look. Trouble is, there aren't many available for the Passat CC, and it's hard to find one for any car for less than $300. I set out to build one for 1% of that price, and as you'll see in this video, it worked!
