The reason that the catylitic converter is hot is because of a rich condition in the engine, one cylinder is not firing. This is most likely the cause of the back fire that you are having. It may be related to the tapping sound if it is a valve that is bend or broken.

Check all wires around your replacement piece to insure that nothing came loose or is grounding out, it may have also overloaded a fuse if one wire is touching another, so maybe check fuses if nothing else.

Pro & con

Upside Sleek and dignified design inside and out, pleasing blend of ride and handling, powerful V8 engines, sophisticated safety features, all-wheel drive available on both sedans and wagons. Downside More expensive than competitors, confusing control layout, electronically controlled brakes lack progressive feel. What's New for 2007 Most of the changes to the 2007 Mercedes-Benz E-Class relate to engine upgrades. Mercedes' AMG division has renamed last year's E55 AMG as the E63 AMG in light of its more powerful 507-hp V8 engine.
