does anyone kno why my headers would be glowing red??
 
Clogged cats. 100%
 
I had this once, and my cat wasn't clogged...the fuel mixture was too rich...but mine was carbed and needed adjustment...not sure if you can run the FIs like that unless you've got codes...

If the CEL light is on...or even if it's not...try pulling the codes...
 
I suspect an unplugged SpOut would accomplish this too.
