Right...there are the 2 brackets that bolt to the back of the manifold and the LIM...you need those...you set a penny in the back of each one...RTV the crap out of the penny so it creates a seal, let it dry for a little bit...then bolt it back up to the manifold/LIM without the EGR/tubes. It'll throw a code, but it'll run better...plus you don't have all that hot exhaust gas going back into the motor...stupid.
