Excellent product

So I was on the hunt for a new BPV and it started off on the wrong foot. The 1st well known brand BPV did not like my car/setup or it was defective. Either way it caused all kinds of problems so I turned to MAPERFORMANCE for some help and recommendations. After a few conversations they recommended Go Fast Bits Mach 2 Recirculating for my car and I could not be any happier. The customer service I received from the entire team at MAP was outstanding. The BPV is well built, easy to install, and even gives you some added features like a conversion kit(sold separate)to convert it to VTA. However pair this with an intake and it makes a very attractive sound that not only you will hear but people next to you will hear. I smile every time I hear it.
