Blow Off Valve Install and Benefits?

[miggzy]

Hi, I saw this online when I was looking for parts for my i4. I thought they came with Blow Off valves already. Are there any benefits to a Blow Off Valve, does it make the turbos sound better? If anyone has installed one can we hear what it sounds like and how the install was pls? Thank you.

Never used this product but years ago when I modded my Mr2 Turbo, I installed the HKS SSQV (the infamous high pitch whistle). It makes your car run rich which may throw a code. Your best bet is to install an intake to get a larger funnel sound.
