Lighter = Faster (N/A build thread #2)

The most effective heat shield is to place a sheet of aluminum between the exhaust and the body. Leaving an air gap on both sides and attaching the heat shield to the body not the exhaust. If you still have the factory heat shielding, it works better than any stick on alternative.

:edit: Pete beat me to it. I really must learn to type faster.

Had to chuck the stock heat shielding because it didn't fit with the Defined Autoworks header. I'm looking into wrapping the header and adding that reflective insulation stuff to the firewall and underneath the car. The latter depends on how much space is left between the manifold and the body and if the insulation will adhere to the bedliner coating. If that works I won't need anything inside.

Maybe you can fabricate your own heat shielding out of some sheet AL that uses some/all of the stock mounting points that will fit with the header?

That's another option because I did keep all the heat shield mounting points. One thing I did before taking the car to the body shop earlier this year was bang in parts of the firewall and transmission tunnel. Hopefully that gives me a little more room to work with. Unfortunately with no engine in the car it's hard to line everything up.
