"Overall I would highly recommend these converters -mounted up factory fit-cleared codes and driving great- could not beat it for the price." posted by: Logan on March 17, 2014

"when i started to bolt heat shields back up to the exhaust tubes there was only two bolts where as factory one uses three for inner near engine block and the outer facing the fire wall. while bolting heat shield to the fire wall side of exhaust tubes the hole for the sensor making difficult to put a socket on it to tighten it to the unit ( had to bend the shield 1/8 inch to go over the flange so i get socket on sensor ) so now time to bolt up the exhaust pipe to the catalytic converter i put second sensor on no problem goes on fine now we go to the bolting on the exhaust pipe to the converter ( we find that the new converter is about 1/2 shorter than factory making very difficult to bolt up (no nuts to screw into like factory flange) had to get help to bolt on at that point. so now we have the support bracket to install 1/2 inch to long now so make spacer to take up space between flange/brace needed bolt/nut with lock washer long enough bolt to brace and flange. Just seems to be missing things for assembly to me that should have been included" posted by: kem on April 29, 2013 view all 2 reviews

Rating: (see review/s)

"I had replaced the exhaust manifold and catalyst on my 97 Honda Civic almost 4 years ago. I recently did some work on my car and noticed that there was a putting sound from the exhaust. I removed this manifold and found that it was cracked in three places. Exactly where the OEM manifolds crack by the O2 sensor and 2 places on the back. They replaced this unit for free but I had to pay shipping for my old units return. Im not sure this is all they crack it up to be being that its supposed to be an improved design...looks like the manifold is worse off than before." posted by: IHredneck on January 8, 2014

"I purchased this product liking the two piece design. Just in case the manifold cracked again not expecting it ever to do that. I ended up having it on for about 4 years and noticed a putting sound when the car was cold from an exhaust leak. Thinking it was anywhere else besides the manifold. I pulled the shroud and there was a crack down the middle by the O2 sensor just like the OEM one had. Took it to a friend and he welded it up and it sealed great. Went to drive it again after it cooled down and noticed it still was leaking. Had someone put a board over the tailpipe to build pressure and I felt a leak on the back side of the manifold. Frustrated that an improved design would break in more than one place I pulled off the manifold and down the back in 2 places where cracks over an inch long. Having my friend weld those up too...I should have gotten the extended lifetime warranty on this product...sorely disappointed" posted by: IHredneck on December 5, 2013 view all 9 reviews

If it wasn't for the Honda Civic's catalytic converter, the vehicle would be constantly spewing toxic gases into air. Catalytic convertors contain a catalyst that reacts with the noxious gases formed from the engine's combustion reaction and turn them into less toxic substances. These catalysts are often precious metal like platinum or rhodium which is the reason why replacements can be expensive. Catalytic converters are especially important if you want abide with local emission laws which are different depending on the state you're in. Some signs of catalytic converter failure are loss of engine power, high emission levels, foul odors from the exhaust and rattling noises when the engine is on.

Frequently Asked Questions

Ask APW
  • Are Honda Civic catalytic converters legal in all states?
    Answer: Every state has its own laws on vehicle emissions and legal limits will usually differ. Among all these states, California is recognized as having the strictest emission laws in the country. As a general rule, if the converter is legal in California, then it is legal in every other state in the America. There are catalytic converters that are legal only for the 49 other US states, which can be a practical choice for drivers who have no plans of going to California in their Honda Civics any time soon.
  • How much do they cost?
    Answer: Catalytic converters can be purchased anywhere from $50 all the way up to about $500. Factors affecting prices include the build of the converter, the catalysts used and whether or not the converter is legal in the state of California. Buyers should generally get the sturdiest catalytic converters they can buy so they won't have to worry about it ever again.
  • How often should catalytic converters be replaced?
    Answer: Catalytic convertors will usually last a vehicle's lifetime, which is around 100,000 miles. A lack of moving parts in the converter means that they don't need any regular maintenance. As long they don't get damaged or worn out, they won't usually need to be touched at all.
  • What are the symptoms of a broken or malfunctioning catalytic converter?
    Answer: Since a catalytic converter's main function is to convert toxic fumes to relatively less toxic gases, a noxious odor from the exhaust system can be a good indicator that the converter is malfunctioning. The engine of the Civic will also begin to feel a bit underpowered. If the converter becomes damaged, it may also begin to rattle against the underside of the vehicle when the engine is running. Emission tests may also reveal an increase in toxic fumes released by the vehicle.
