I recently finished swapping in a used 2006 rsx type s from LKQ into my 05 rsx type s, i also installed new headers. I noticed on the first start on the motor, the headers turn glowing red. Why is that? Any help will be appreciated!

I'm not sure a header or exhaust manifold will go bad and glow red

Check to make sure your exhaust isn't clogged up somewhere, the cat, etc.
