Hi Adam,

I used the ACL heat shielding above the extractors (sikaflexed to the underside of the body), it's good stuff, easy to shape and insulates well.
I clad the engine bay with powdercoated 1.2mm ali and stuck high temp silicone cloth (from a ship insulation supplier in naval base) to the back of the sheets.
Ceramic coating the extractors also helps, the laser temp gauge suggested about 100 degrees cooler than the sidepipes whilst on the dyno.
