For a muscle car like the Pontiac Grand Prix, a powerful catalytic converter can be just as good as any other performance upgrade. The main task of your cat converter is to reduce and convert harmful emissions from the engine into less harmful compounds before it is released into the atmosphere. But aside from helping lessen air pollution, a superb cat converter also helps ensure optimum engine performance and max fuel efficiency. It is always a good idea to replace a faulty cat converter immediately rather than be discouraged by the price tag of a brand new cat converter. Ignoring a damaged cat converter will cause other exhaust system components to break down as well which results in a repair bill that is much higher than the average Pontiac Grand Prix catalytic converter cost.

Frequently Asked Questions

Ask APW
  • How much is the expected Pontiac Grand Prix catalytic converter cost of replacement?
    Answer: It is normal to shell out about 100-250 bucks for an average catalytic converter replacement on a Pontiac Grand Prix. However, there are some universal catalytic converters that go for as low as 50 bucks and a couple Pontiac Grand Prix catalytic converter high quality replacements that can fetch up to 600 bucks.
  • Is there any way of knowing if the catalytic converter on a Pontiac Grand Prix is going bad if the check engine light does not go on?
    Answer: Even if the Pontiac Grand Prix doesn't throw a code, the vehicle will still exhibit common signs of catalytic converter failure. For instance, clogged cat converters typically result to a loss of engine power, acceleration issues, and a really noticeable reduction in fuel mileage. Unfortunately, plugged Pontiac Grand Prix cat converters are a common issue so it's best to have the cat converter checked as part of the regular tune-up.
  • What causes a Pontiac Grand Prix to get red hot? Does this mean that the catalytic converter should be replaced?
    Answer: A red hot catalytic converter typically results from too much unburned fuel being sent to it. This is usually a problem with the other components such as the oxygen sensor or spark plugs than with the cat converter itself, so it's a good idea to have the root cause checked. A red hot Pontiac Grand Prix cat converter won't have to be replaced unless the heat had already damaged or collapsed its insides.
  • What does the label '49-state legal' for replacement Pontiac Grand Prix catalytic converters mean?
    Answer: A catalytic converter that is labeled as '49-state legal' means that it can't be used for--or sometimes even shipped to--vehicles in the state of California, but is perfectly fine anywhere else. Since California imposes much stricter laws in terms of vehicle emissions, more production and material costs are required to make cat converters that meet these regulations. Because of this, many catalytic converter manufacturers opted to produce cat converters that don't comply with California's emission laws. This is good news for vehicle owners who live outside California since they can get legal, high-performance cat converters that are both cheap and efficient.
