Frequently Asked Questions Ask APW
Are there any benefits on upgrading to a high-flow catalytic converter from a stock one?
Answer: Full-size pickup trucks like the Dodge Ram 1500 can especially benefit from a high-flow catalytic converter, as it can help process the exhaust from large engines more efficiently. High-flow catalytic converters are also less likely to get clogged than standard catalytic converters, making them last longer. What's more, as aftermarket catalytic converter manufacturers design high-flow converters to comply with tight emission controls in states like California, switching to a high-flow converter can also mean compliance with state requirements for carbon emissions, thus saving money in the long run.
Is it normal for the catalytic converter to whistle?
Answer: A whistling sound coming from the catalytic converter indicates a clog in the catalytic converter. This whistling sound usually gets louder when the accelerator is applied or when the driving at high speeds. This may come with a rattling noise when the truck is idling. In such cases, it is highly recommended to get the catalytic converter checked for problems and replaced if necessary.
What causes the Dodge Ram 1500 catalytic converter to overheat?
Answer: There are many reasons why a catalytic converter overheats and causes the Check Engine light on the dashboard to come on. The most common cause is the oxygen sensor malfunctioning and sending the wrong signals to the Dodge Ram's powertrain control module. Leaking fuel injectors may also lead to the catalytic converter overheating, as leaking unburned fuel will burn and melt the substrate inside the converter.
What does "gutting" a catalytic converter mean?
Answer: Gutting is a temporary solution to restore exhaust flow in a clogged catalytic converter. The process basically involves breaking down and removing the ceramic material inside the catalytic converter using a pry bar, hammer, and a heavy-duty vacuum. This essentially removes the clog inside the converter but also renders it nonfunctional. Therefore, it needs to be replaced as soon as possible.
