Stainless Steel Turbo Heatshield & Outlet
In the interests of minimizing radiant heat within the engine bay, since I no longer have the OE double-walled manifolds, I set about designing a 0.6mm thick mirror-polished (on the inside surface) stainless steel heatshield to box in as much of the hotparts as practical, and also wrapped the downpipes for good measure to further help keep underhood temps down. I made a pilot batch of 10 of these heatshields if anyone is interested, fits right on top of the OE solenoid heatshield bracket - PM for details..
Also designed my own outlet, with full flow 1.75" ID connections, with a good shallow-angle merge into a 2.5" ID, and wrapped the whole thing in gold foil for good measure. Fits very well onto the car, and will never burn up due to being very far from any major heat sources.
