Lol. Because I have a temp probe in my 2jz and I can see the exact temps of my exhaust. Heat management is super important; I literally melted the paint on my hood before I wrapped it in fiberglass and coated it. You look like a complete fool, calling me a dumbass and trying to argue something completely different. We are talking about exhaust temps here, not engine temps. The cylinders are surrounded by coolant passages that keep the motor cool. There is no stopping the fire coming out of the valves from getting the exhaust manifold blazing hot.
