Hot enough to tatoo the part number (cast into the manifold) on your forearm if your not careful.

A modern engine with a proper control design will run stoichiometric A/F up to just shy of the point the catalytic converter is damaged, which is about 1500 Deg.F. at the catalyst inlet. This approach maximizes fuel economy and minimizes emissions on the Federal US06 emissions cycle. These high exhaust gas temperature will heat up the exhaust manifold to nearly this level if the vehicle runs high RPM and load for a sustained period, like towing a trailer up a mountain in a low gear. It will also approach this level at one approaches the maximum rated speed of the vehicle in something less than top gear. In either case, if the driver depresses the accelerator to the floor a rich fuel may be legally used and the temperature will drop 150 Deg.F. or so degrees.

exact temps vary but run in the range of 1200 degrees. if your catalytic converter gets plugged it can increase that temp to over 2000 and make pipes get cherry red,or start a fire.I wouldn`t try to touch one after a car has been running more than a minute or even less.

exhaust gases can go as high as 1200 degrees :(

hopefully you're not trying to figure out if those are 2nd or 3rd degree burns on your fingertips. DO NOT use a rectal thermometer to find out it will explode on you showering mercury (bad for you) all over.

1200 degrees depending on how hard you drive.
