Allow me to rephrase. I understand the exhaust side runs hotter, but from the research I've made, mine has been running hotter than usual. Before upgrading the radiator and the fan, I was regularly on the verge of overheating. So far, I've only had one instance in the summer where I was getting into the danger zone for temps. Are there any threads on the forum you would recommend that would suggest upgrading the stock exhaust manifold?
