This thing sounds great when driving. I like the fact that you can control how much is recirculated and how much goes to the atmosphere. I recommend going for a test drive so you can make adjustments before putting the underbody tray back on. It really only activates when you step on it, so it’s stealthy when you need it to be and can be loud when you want to have fun!
Installation would have been much quicker if I had a flexible drill bit extender. It’s very tight down there, but that’s more of Hyundai’s issue. Also for the Veloster 1.6T gen 2 you need to go from the bottom. The whole thing will probably only take 20 minutes with the proper tools. The BOV/BPV is very well made, solid aluminum vs the stock plastic one. Definitely recommended to get for a quick easy mod and to have some fun.
Outstanding quality from GFB and customer service from N75! Install is much easier from under the car (lesson learned there). Paired with the Pierburg bov solenoid. No check engine light or other issues! Sounds AMAZING!
