Very true , but I was thinking if he has a 210 model the manifold is probably well gunged up by now (unless it's been done before ) ?You can do that too, althought that requires the manifold to be removed. If the manifold is clean and they are not causing issues, I would keep them connected, as they do increase torque and MPG.
