Nahh i dont own one.
There are shops here that sell mandrel bent pieces and straight pieces in both stainless and mild. My friend who owns a tuning shop (being built) has the equipment for fabrication so being able to make one will be easy

A friend of mine had one built for his 2000 type r integra that cost $480 in polished 3" mandrel bent fitted with a k & n filter from one of the shops here.... which imo is quiet expensive. So yeah DIY is the way for me
