I pulled the header off my car(that the previous owner put on), and from pictures i can tell its not a RB, or SDJ, so im assuming its a pacesetter but i cannot find any pics. and i dont know any other header companies. had to post becuase it is bugging me to know the brand.

 

i had a crappy pace setter and that is not one. it might be a one off ? especially with that american three bolt header flange on it

 

looks like a home built unit, a well put together header but home built non the less. i think this way because i know of no company who uses the 3 bolt collector and it was mig welded not tigged.

 

Thats what I was thinking, its odd that the o2 bung is straight up too, makes it easier to change but all of the RB ones I have seen are angled.

 

i can't tell for sure but is that stepped? post the pipe diameter.

 

2 inch all the way. and i did notice the 02 sensor is easy to get on and off

 

hmm not racing beat....kinda looks like home built... monza/pacesetters would be one full piece like racing beat
