Ok, here's the story: I got a solid diff. mount, new tranny mounts, throwout and pilot bearings put in this week. I picked the rx today, paid the $509.25, and drove to work. I would have done this myself, but I don't have a lift or a garage so i paid to have it done. When I got to work, i layed down and checked the the underside of the car to make sure everything was ok, (probably should've dont this before I left the shop), and saw that they had put my exaust back on with ZIP TIES!!!! WTF!!!!! So anyway i plan on calling and/or showing up at the shop tomorrow and asking them what the hell. So, I know our cars' exaust gets really hot, but how hot exactly? Hot enough to melt a zip tie? Any suggestions as to what I should do in this situation would be great.

i would think so, my presilencer is pretty blued from the heat.

ya they will melt as soon as your car is up to temp, i think normal exhaust will reach 1600 rotary exhaust probably 1800(this is the air of course, the pipe will not get that hot)

If your exhaust is anywhere neer 1600 there is trouble

I heard 760F was pretty normal, but thats off the top of my head (Read: probably wrong)

That's how hot exhaust gets.

There is a product called thermal ties that looks like zip ties but is made for exhaust components. they sell them on smp' site. Maybe they used these.

holy flameballs, thats the craziest picture ive ever seen

copied from some exhaust temp guage site...

As the engine works harder, the temp of the exhaust gases increase. In a naturally aspirated car, the EGT at full load might be 700 - 750 degrees C if the mixtures are correctly rich. If the air/fuel ratio is overlay lean, this temp will dramatically increase to perhaps 850 or 900 degrees. In a turbo car, pre-turbo temps of 900 degrees are common at high loads, with post-turbo temps being 800 degrees or more. So as you can see, turbo cars run EGTs much closer to danger. Some turbos are rated at 900 degrees continuous, but - in the real world - if you measure anything over 800 degrees C after the turbo you're starting to push it a bit. However, as with all gauges, the worth of an EGT is in spotting sudden changes away from the norm - they could be indicative of a blocked injector or some other problem with the engine fuel, boost or ignition timing.

750*1.8=1350+32=1382F and a rotary's exhaust is much hotter so ya about 1600F

im sorry but that looks a little photochopped

Yeah I just stole that pic from another exhaust thread. Thought it might serve nicely here.
