Don't even think of getting an after market manifold if its just for the looks, they do next to nothing unless you are a track racer dude with hardcore supporting mods and tuning. Also Once the aftermarket manifold is installed, you can no longer use you top mount anymore, the manifold is simply to big and the intercooler itself will be resting on the manifold and the intercooler inlets dont line up with the turbo and throttle body adapter. This means that, you'll HAVE to relocate your battery and change to a front mount intercooler set up even if its not what you are after. Stick with the heat shield chroming idea, I reckon that looks mint!!
