Anyone have tried this Headers?

OBX Racing SS Exhaust Manifold Headers Lexus SC400 SC430 GS400 GS430 LS430 NEW

 

I remember before I purchased my PPEs I was looking around and someone posted that the OBX headers didn't fit well and were, in general, poorly made. I'd just go for the PPEs if I were you. They're expensive, but have documented proven gains.
