My impression is that headers that come finished with ceramic coating is not as good as a dedicated ceramic coating shop. So that is the way i plan on doing it, buying them with black protective coating and have a local to me shop sandblast, prepp and coat them. planning on contacting this company that is 63 miles from me : https://www.fiskes.no/bil/mc/
And yes it is the 28150 headman i have now, i needed to bang 1 tube a little so i expect no less from 2" primary. I can probably re-use my ball & socket collector reducers since i have O2 bongs in both sides.
I really like the ball&socket style flange as you can angle the exhaust pipes sligthly up/down/left/rigth etc. insted of doing pie cuts on the pipes to get a good angle.
