Extractors / Headers to suit C4

<< < (6/6)

White88:
So I take it 87Z51 you don't run an air pump system with the pacemakers, as they don't come with them , do have any problems come rego time.

77CVT:
I would imagine they wouldn't know if it was supposed to have an air pump or not.  Emissions tests are easy as you just play with the timing.

White88:
That's what I thought , I don't think late model engines have air pump's e.g. LS1's and such. My son has a late model monaro and I don't think it has a air pump. If all the plumbing is removed from the car they probably wouldn't know any different.

87Z51:
Never had a mechanic check emission gear on any car.
If you were worried about it , would be no problem to weld the EGR riser off the old manifold on to the new headers in the same position so as to retain EGR.
Some brands of header available in the US have this provision for California  cars
