Quick Question About Header, Specifically speaking Pacesetters... Options

[ExSane]

I've found a couple of Pacesetter Headers for the 7A-FE. I decided that I wanted to go Pacesetters becuz the eBay ones for the Corollas header designs are kinda weird looking. They have one piping that bends kinda crazy that looks like it'll slow down that cylinder's exhaust flow. And I looked at Pacesetters and they have Y shaped pipings which is better than the eBay designs. But anyway, I've noticed that the 'polished coated' costs alot more than the 'black coated' ones. I decided to go black becuz of the amount of heat headers create, I'm thinking black will help it reduce by a bit. But then I've been told by my friend that the black Pacesetter headers paint chips off. I'm thinking about throwing 2 layers of High Temp Clear Coat on. Do you guys think it'll help the paint stay on instead of chipping from the vast amount of heat?

you have to have a shop weld in a bung for the screw in O2 sensor.
