Extreamly hot exhaust temps?

Ok, so getting out of the car i hear that sound of super hot metal tinkling... i walk around back and tap my finger on the exhaust tips for maybe 0.000000000000001 of a millisecond (ok well close enough).. and i damn near burnt a blister on my finger.

I wish i had a temp guage, but i know i could cook a steak on it. I dont think i've ever had a car where the exhaust tips got that hot.

do our cars shoot flames out the back or somehting?

rotaries have much higher EGT's than pistons.

and also yes, if the conditions are right.

Yes......they do!
Hot MF's aren't they..................bet you don't do that again.
I wipe my tips off everyday when getting home from work if there is some oil spooge on them and even using a towel, you better not have it on there to freaking long.

from what I recall, my egt's were around 1,200F at idle, 1,600F cruising around, and 1,800F range accelerating. You should be able to get to 2,000 F

you can see how quickly a cold engine heats up around 40 seconds in on an old video of mine:

Hah! I got burned on my left shin like a week ago when I inadvertenty brushed my bare leg against the exhaust (RB) tip. This was like the second time I did that. The first time was a good 6-7 years ago (Greddy exhaust on my Eclipse).

Yes, Exhaust should be HOT. especially after it has been driven for a while.

You will not shoot any flames UNLESS your Catalyst Converter is out.

There is something wrong with your car. Your exhaust should measure around 40F even at 9K rpm in the summer.

I understand that exhaust temps are extremely hot, but I just found it odd that the tips themselves were so hot. On my other car the heat doesn't make it past the muffler, so i thought it was out of the ordinary

What do you use to keep the exhaust tips looking nice

My car now has 500 miles on it and the bottom of the tips are all black - like soot has been dripping out!

You'll get different opinions of course, but this is the best by far IMHO!

http://www.englishcustompolishing.co...hotchrome.html

Now I have the RB catback exhaust, but to tell you the truth as I said above. I keep a towel in my garage right near where I get out of the car. And when she's put away for the evening, I will wipe the tips, (just where the soot gathers, usually there right at the bottom) as it's much, much easier to wipe off when it's hot and still kinda wet. I just make it a habit and now I don't even think about it, nor do I have to do it every single night. Use the Englsihcustom stuff probably every other waxing or as needed.

Yup. Rotary gets pretty damned hot. Don't touch it again.

I have a Greddy SP2 catback with the huge, protruding exhaust tips. I have a nice scar on my lower calf due to the high temp exhaust.

Get some Dry Ice 100% alcohol Injectors for your exhaust, yo.

If you blast the exhaust tips with liquid nitrogen, it will help to cool them.
