I love the way my 180's look and sound. The key with the heat issue is to have them coated. I took mine to HPC right after they were made and had them coated inside & out. You can put your hands on them within a minute of shutting down the engine. I have a heat shield on my deck lid, but do not know that it is necessary (although I have always heard that it is). Yet when you look at my headers you will notice that they pass within a half of an inch of my painted engine bay with no problems. And yes I have had this car on several long distance runs, at high speeds etc., in Arizona, with no issues. The one problem with these headers is taking them off or putting them back on. It is a royal pain! It took 3 of us, three hours to get them installed last time, and you would think that it would be easier because there are no gaskets! All of the flanges were cut with the wetjet process and port matched with the heads and use no gaskets. And if built right they will make horsepower.
I have a second or thirdgeneration Hall set.
They aren't as pretty as some of the others BUT they are much easier to install and remove at a moments notice.
On this car that is important to me.
As far a HP goes I can't think of anyone who has done a dyno test to prove anything. I would think that much like running Webers there is little point to running them on a stock engine.
The gain is defiately going to be an upper rpm one and probably, like most headers, loose HP down low.
