convertersAnother contributor wrote in that he removed 2 of the 4 converters ( repositioned the O2 sensors ) and finally got the 22mpg as advertised by Ford ( previously only 17mpg )without causing any engine codes. It seems logical that without the added restriction that more power and torque would be available. Messing with the emissions system is illegal and I would definitely recommend replacing the muffler.

What is the difference between a Catalytic Converter and a Universal Catalytic Converter?

Direct to fit Catalytic Converters come ready to install with all parts pre-welded. These are better for the DIY professional. Universal converters are cheaper, but require cutting, welding, etc. These installations are best left for the shop professionals.


Catalytic converter replacement?

A factory catalytic convertor can be mounted to the exhaust manifolds and muffler pipe through hardware fittings. Original Equipment Manufacturer (OEM) catalytic converters will be a direct replacement and not requiring the cutting or welding of the exhaust system. In contrast, aftermarket "universal" catalytic convertors may have to be welded in or mechanically fastened on through screw-tensioned clamps.

What are the disadvantages of the catalytic converters?

Well one example I know of is I have a 1995 cheverolet silverado with a 5.0 v8 and I heard that cutting of the cat helps give me 20-30 more horsepower. Not as much resistance for the exhaust to go through if you take off the cat with all the baffels and other things inside it. If anyone was going to put true dual exhaust system on their vehicle it would make it louder and better. Know that it is illegal to remove a catalytic converter from any vehicle. Also any vehicle with the OBD2 system will not run properly with the converter removed.
