I am suspect of the catalytic converter(s) on our 460 powered F-350. It has lost some MPG and seems to have also lost a little snap.
When cold, it is now emmiting that "rotten egg" smell normally associated with failing converters. This is recent as of the last month or so.
I have always had to replace converters due to poor performance or no performance. I have never had any bad ones that weren't almost completely plugged up and caused exhaust to be extremely hot.
The truck still runs acceptable, but really stinks when cold.
Anyone have an real world experiance with their Ford trucks and converter failure?
New ones for this thing cost over $600.

I haven't had any problems with mine in the 83k I've had it,Alex. Do you think an oxygen sensor would help? You do haul alot,so the engine will call for more fuel under load. That truck has 2 cats,right? A pre-cat and a small cat.

Yes it has two Mike.
There are no codes to indicate a bad 02 sensor.

In Georgia if a truck is over a certain weight then the emissions test is not needed, we just yanked the converters, sure did run better after that. Most F-250 and up are exempt here.

Why don't you just get a set of mud runner headers that come up through the hood?

The milage is getting worse. I think that I'm just going to bite the bullit and buy some new converters.
Anyone have any used ones they took off of their 460 F series when it was new?
