I've been considering getting a header for my ITA MR2, and have been looking for a 4:1 header. The only one that is available that isn't cu$tom made is made by pacesetter for the Corolla. Good news is it is dirt cheap.

Here's the question - I can get it for $140 or $100 more for their Armor ceramic coating. Should I bother? Any effect on performance or underhood temps? Or should I just wrap it to keep the underhood temps down. The header runs close to the starter - so temps are a concern to me.

Here's what they are offering: "ARMOR*Coat, a polished, 2000 degree F metallic-ceramic coating. Each header undergoes an extensive perparation phase followed by two applications of the coating and a high-temp curing process. The ARMOR*Coat won't discolor like paint, chrome or dull finish coating, reduces underhood temperatures, resists rust and corrosion and is easy to keep clean."

I coudn't care less about how it looks, so if this is just so it's pretty - I'll get them uncoated.

Thanks!
