Umm, maybe.

Depending on what exact vehicle they came from, they may work. You will just have to try. Even if they will physically clear, you may still need to modify the exhaust pipes.



But my question is why?

I can't see any real performance gains to be had. With very few exceptions, all of the factory manifolds are poor performers.

If you are replacing a damaged piece, there are still plenty of 70s manifolds out there.

Doing more with less, or something like that.

You might need some Titanium rods and a flow bench!  LMAO on floor

I honestly don't get it.
