Catalytic Converter Heat Shield
#16
Ripped mine off my coupe due to rattling. It made the car growl bit louder, in a good way though, like you have an aftermarket intake. That's the louder sounder people hear and its because shield also muffled the sound of the exhaust. I just bought some exhaust heat wrap and wrapped up the same area to mitigate the heat and dry grass issue. But there's no performance issues is taking it off.

G35 cat heat shields

Had to remove heat shield (badly rusted anyway) on my G35 to reach 3rd bolt to remove cat to replace front propeller shaft. Don’t know what to do about wrapping it with some sort of heat tape ir leaving it alone. My concern is heat on floor of passenger compartment. Any ideas??

My 04' was from a salt state and when I bought it both cat pipe shields were rusted and making tons of noise. I just cut them off and haven't had any problems since. You won't find too many shops interested in trying to weld old rusty metal. You would probably have to cut the rust areas out and add in new metal which would just cost too much for an old set of cats. Honestly I would just order a set of test pipes and weld in hi flow stainless bullet cats on each side to replace the old ones if yours are really really bad.
