No matter what type of engine is installed in your Jeep Grand Cherokee, it will surely produce gases that need to be expelled out of the vehicle. These combustion by-products usually contain noxious substances that need to be converted into less harmful emissions before going out of the car tailpipe. This is why the catalytic converter is made. Without a well-functioning Jeep Grand Cherokee catalytic converter, your ride will give off gases that are dangerous to the health of human beings. It will also produce pollutants every time you take it out for a drive. You will surely experience high levels of emissions, loss of power, rattling, and a lot more problems. If you don't want any of these to happen, replace your defective cat con with a new one right away.

Frequently Asked Questions

Ask APW
  • Is it possible for the Jeep Grand Cherokee catalytic converter to restrict the exhaust system instead of reducing the vehicle's harmful emissions?
    Answer: Yes. The catalytic converter in the Jeep Grand Cherokee will be useless and will just become a restriction in the exhaust system if it is not installed in an area where it can work at 450+ degrees F. If the cat con is operating well, the exhaust will flow smoothly due to the high velocity and heat of exhaust gases. In the process, the noxious gases present in the exhaust will also be reduced. A properly sized and correctly installed cat con presents almost negligible resistance to exhaust flow, so the Cherokee's horsepower and torque won't be affected.
  • Why are most catalytic converters 49-state legal only?
    Answer: All 49 states, except California, follow the guidelines set by the United States Environmental Protection Agency regarding the requirements for automotive catalytic converters, so those who live outside the Golden State can use EPA-approved (49-state legal) catalytic converters. California has additional laws set by California Air Resources Board (CARB). Jeep drivers residing in this state need to install a CARB-approved catalytic converter for their vehicles to be street legal. All the cat cons installed or sold within the Golden State should be tested, approved, or officially exempted by CARB. Additionally, all the cat cons for sale must be brand new and ARB approved.
  • Is the Jeep Grand Cherokee catalytic converter responsible for that "rotten-egg" smell coming from the exhaust?
    Answer: If the rotten-egg smell is during the Cherokee's first start-up, this is because of the rich fuel condition in a cold engine. But if the smell remains even if the engine has warmed up, it can be caused by a defective catalytic converter. The foul odor comes from excessive monolith due to wrong fuel or rich fuel mixture. Improper mixture of fuel also causes excessive hydrogen sulfide in the vehicle's emissions, which results in rotten-eggs odor.
