The install was fairly straight forward. I definitely hear my stock BPV and intake sucking noise now! I haven't noticed any power gains YET. I'm too enthralled with the sound! I'll make a video and link it here later.
No noticable power gain...what!!! That was the first thing I noticed with the Cobb, but the sound is to die for too. A friend of mine said the same thing about the HKS SRI that he didn't notice any power gains...
