Since i probaly wont get any responces in the Integra Section ill post it here too

Are these Stock Welds on a 90-91 Integra B18A1

 

hell no those arent stock. i wanna say it looks like someone ran direct port nitrous maybe? thats weird.

 

i think there EGR cleanup ports, like the car had a EGR clogging problem so they drilled the manifold went in there with some sotra wire brush probably and cleaned the inside of the manifold probably, the either welded it up or sent it out to have it welded up real quick
