i would like to go ahead and eliminate my egr system, however i have one dilema. (maybe just a mental block) its more than easy to remove all the components, and to make a metal cap to bolt down where the valve used to be on the intake manifold. what i cant figure out is the lower connection on the exhaust. it appears to be a tube slid over a flange, and bolt clamped on. how would i make something or find something that takes the tubes place and clamps on, and sealing it up tight? any input is appreciated.
