We removed the heat shields on the manifold on my 07 2.0L SE i was wondering how much will the temps go up without the heat shields on there?

It wont catch the firewall stuff on fire or anything with them off will it?

The shields just look like tin foil buti figured they are there for a reason.

I cant get my car in to get the header put on till monday so if i had to drive it i didnt want to burn up. [:(]

U should be fine. But I know a couple guys with the 2.0 who have a header and they have less clearance to remove the stock exhaust manifold out from the top than the 2.3 does. So when you put ur header on it may be a lot more difficult to install. Just a heads up.

I've had mine off since I installed my header and haven't had anything catch on fire , but I did see some light rust building up over time and got some header coating that you brush on from Eastwood.com that keeps the rust away and suppose to keep it cooler.

Well i was talking about the stock heat shields and the stock header/cat.

I figured they put the heat shields over the stock manifold for a reason and since we took em off i wasnt sure how hot the stock setup would get with em off.

Well considering a cat can get up around and over 1000 degrees and theres one attached to the manifold...
i just needed to drive it for a few days and i wasnt sure how hot it would get with the heat shields off. I just drove it about 15 miles with them off then the next day i put the header on with the wrap.

If you stomp on the go pedal, the cat will get up to about 1600*F, that was verified with a scan tool viewing live datastream. From what I understand that is the internal temp of the cat. So if you drive the car gently with the heat shield off the manifold, you should be ok.

I've currently had the heat shealds off my mani-cat for months, and haven't had a problem. However I did notice the sound of something steaming one day, so I popped open the hood and saw that the condensation from the A/C pipe was slowly dripping onto the mani-cat, turning into steam as soon as it touched it.
