Anyone know if this system will work on EFI manifolds?

Not sure what you’re asking here. You are talking about exhaust correct?

If the header will work with the stock 280z intake manifold.

If the supplier states it will work with year,make and model I’m curious what your concern is.

Are you buying a new system or trying to figure out if a used system will fit the car? Need more information

I'm trying to figure out if this system will fit my Z. Its a 76' with the stock intake manifold. Everything I've read - from the supply side - states that these are for triple carb setups and am wondering if anyone has tried doing it on the EFI cars.

I have this system on my 240z with SUs. The header simply bolts onto the head (obviously) and I had the header ceramic coated to keep the heat down. I know nothing about the efi systems on a 280, but if it is all on the intake side like a carb then you could have heat issues or more likely fitment issues. The header mounts cleanly on my head, I bet it would on your 280 but without knowing first, it could be a very costly error. And I'm the king of costly exhaust mistakes...

Are you buying these from a supplier? If so it should state the fitment parameters. Gotta know more details. Is this exhaust new or used?
