they actually have wraps that you can buy to put around the parts to keep a lot of the heat in just for that reason. start with the exhaust wrap which can cut back the heat up to 45% and give you MORE HP. Here is a link for the exhaust wrap http://www.importperformanceparts.ne...haustwrap.html

You can also check out for other wraps for the engine as well that could help you out. Let me know how it works
