Also, what is a "bung"? I don't understand the difference between the delete pipes with and without a bung I guess.
Thanks (also, my first post here, yeehaw!)
They make block off plates for both ends of the EGR that fit between it and the gasket. That should take care of anything getting back into the engine. If you are removing it frome the engine, there are block off plates that block the holes.
Bungs are the threaded holes on the exhaust that you sensors screw in to.
