intake mani would still heat up.....but ur a turbo guy...u have to kno just how hot that turbo gets when its been runnin. and yes hotter exhaust is better, but to a point. theres a limit to how hot things need to get, ex temp being one of them. i agree that its still hot as shit under the hood, but the more moving parts (aka turbo) the hotter shit gets. n no matter what, heat robs hp. no way around that.
