You cant buy the HKS low mount manifolds brand new anymore, but they come up on ebay and these forums ocasionally. All the piping is custom, the airbox heatsheild is just a UAS fibreglass one painted black, the heatsheild on the manifold is custom and the wastegate is mounted on a custom adapter to fit the manifold.
Nismoid, I realise that, said I did what I could to make it as stealth as possible...
