Bought from Stephen at IA. The install was a little tricky for me (Iam not mechanically inclined). It took me about 2.5 hours rather than one which some of you wrench types reported. Got it in, took her out and ran like hell with no initial problems. I couldnt hear much difference in the sound. I did notice the car pulls more eagerly (its a stage 1). Something that did surprise me that I did not recall anyone else mentioning was higher peak boost readings. In second gear the car had never pulled more than 0.9bar. After the V-flow it reqularly kisses 1.0 bar in second gear. Subjectively the boost seems to build faster than before but I could be wrong about that.
After about 20 WOT runs the car went into safe mode and I could not get it out by shutting it off. It also had a rough idle and lurched some under light acceleration. I found a couple of O2 sensor hoses trapped under the V-flow box. I freed them up and the problem was solved!
Its a great product and a relitively easy bump in hp. Highly recommended!

 

It's a great mod...but a ***** to install.

I haven't seen any additional boost, but agree with your other observations.

 

I agree, it is a great product that deliveres a noticable gain in performance.

 

I agree it was pretty frustrating to install but I think I could probably do it in an hour or so now....
