Why dont you create a build thread instead of lots of threads of single pictures. Looks nice but the picture has been taken too far away to do it justice.
I have seen them in the front of the manifold so as they are sucked into each port where you can see the 6 different routes on the front of the nanifold.
I think copywrite may come into it. Im sure you could get a machine shop to make them but selling them may be a different story if there is a patent on them.
Have a look at jim Potters build you could see the pipe work at the sides but the intercooler was not in your face for a fully stealth you could go chargecooler
I had Hid's in both high and low beam but realistically it a big expense for high beam when they take a whle to warm up and no good for flashing i had led side lights and i think H7 Hid's for low beam in the projector lamp
I think you need to loosen the dash and pull it towards the passenger seat to be able to get to the pipe inside the a pillar but have never needed to do it but thats what i heard
