im curious if somthing like jet-hot 2000 or similar can hold up to the heat so you can coat the turbo exhaust houseing and surrounding pipes so they dont get all rusty an nasty.

 

I just had mine coated and they are holding up fine. My friend that told me to get mine coated had his coated for two years and still looked great. I used a local guy here that is really resonalbly priced.
I got my crossover pipe coated inside and out, the log header coated inside and out, the turbo housing inside and out , down pipe inside and out, and the cat coated outside only. For all the coating it was only $250. He does several colors, but I chose flat black and it looks pretty good.
