"quality of product great price and fast shipping!!!" posted by: ray on June 25, 2014

"This converter appears to be well built, and solved my P0240 (inefficient catalytic converter) code problem immediately. Can't beat the price and free, quick (3 days) shipping. If your existing front pipe is in good shape, this converter is well worth the hassle of adapting it to fit." posted by: Pistole on September 11, 2010 view all 5 reviews

Your Mitsubishi Galant catalytic converter was invented in order to counter air pollution. Its primary job is to convert harmful pollutants such as nitrogen oxide, carbon monoxide, and hydrocarbons to less harmful substances like nitrogen, carbon dioxide, or water vapor. Just as the name implies, it makes use of two catalysts to do the conversion: a reduction catalyst and an oxidation catalyst. Overuse of fuel additives and leaded gasoline are proven to alter the composition of the catalysts, which can lead to decreased effectiveness of the catalytic converter. A clogged catalytic converter can also mean trouble to your Mitsubishi Galant.

Frequently Asked Questions

Ask APW
  • What is a true Mitsubishi Galant high-flow catalytic converter, and is it legal to use it?
    Answer: A high-flow catalytic converter, as the name implies, allows exhaust to flow through a larger area and thus flow faster than in an OEM catalytic converter. It is regarded as being more effective than a regular catalytic converter because of its ability to increase power by increasing exhaust flow. When catalytic converters first came out, they had beads placed inside a housing over which the exhaust gas got converted and flowed out through the exhaust pipe. A honeycomb redesign for catalytic converters came out much later and was initially called a "high-flow" catalytic converter. The honeycomb design was soon used by most manufacturers, however, and although it became common practice, it is pointless to call them "high-flow." A true high-flow catalytic converter uses an oversized block of material, has larger inlet and outlet tubes, and has a longer tapered section. It is legal in all states except in California.
  • What is the correlation between a clogged catalytic converter and bad fuel economy?
    Answer: Although there is no way to physically check if a catalytic converter is clogged, a noticeable drop in gas mileage is a telltale symptom. A clogged catalytic converter increases the pressure in the exhaust--imagine exhaust gas being pushed through a space that's smaller than it normally flows through. With the engine doing this extra job, it will not be able to perform its normal functions properly. This adversely affects the miles per gallon the vehicle will achieve.
  • What is the simplest way to check if a catalytic converter has failed?
    Answer: Aside from a drop in gas mileage, a failed catalytic converter can also cause little or no power when accelerating. These are simple observations that can be done by the car owner to correctly diagnose a failed catalytic converter. Alternately, the catalytic converter can be detached and then shaken--if it rattles or produces a clanking noise, the honeycomb structure inside must have become brittle and cracked.
