Default what is the hottest our exhaust will get? in degrees farenheit...

my exhaust is hitting on place underneath. I want to make a shim that will fit between the exhaust and that part to stop the rattle. I found heat tape which is capable of taking 270 degrees. I would think that's more then enough... but I thought I should check and be sure. I'm wrapping a towel with this tape and will slide it between the exhaust and body. Then use one piece of tape to attach it. I'm hoping that will be enough. Or any other ideas? bending hanger isn't an option.. fvcker won't move. My issue is at the first exhaust hanger after the DP.

Default IIRC the cat gets as hot as 350C .... I think this would imply that the exhaust will be hotter than

270F....

Default That sounds right. My EGT gauge on my truck can get to 11-1200 pretty fast.

Granted that's a Cummins diesel truck pushing a LOT of boost...... but things get HOT! Even on our little 1.8's

Default check out the link below...

Taken from wikipedia
"....The function of the sensor is to warn of temperature excursions above the safe operating temperature of the 2-Way catalytic converter of 750 Degrees Celsius. Note that modern catalytic converters are not as susceptible to temperature damage, many modern 3-Way Platinum based converters can handle temperatures of 900 Degrees Celsius sustained, while many modern 3-Way Palladium based converters can handle temperatures of 925 Degrees Celsius sustained. Temperature sensors are also used to monitor catalyst functioning - usually two sensors will be fitted, one before the catalyst, and one after to monitor the temperature rise over the catalytic converter core. For every 1% of CO in the exhaust gas stream the exhaust gas temperature will rise by 100 Degrees Celsius. "<ul><li><a href="http://en.wikipedia.org/wiki/Catalytic_converter">wikipedia</a></li></ul>

Default My dad had this problem when he had a trailer hitch installed on his old van...

we took a BIG rubber grommet, cut it in half, and stuck it in between the exhaust and the hitch, SOB never fell out it was in there so tight.
