I can't even believe this channel, saved my life. xD I had to replace my whole suspension on my 2002 Honda Civic Ex after a bad accident. I wouldn't have known how to do it if it wasn't for these videos. So in return for all the information, in a quick, detailed manner, I did get all my parts through them. Same price as eBay, but they won't let you buy things that don't fit in your car and make sure you are getting the right things. I almost got the wrong bolt pattern for my rim, almost got 4x125 instead of 4x100, but they emailed me to make sure before sending and knew the stock bolt pattern and asked if I had an aftermarket Knuckle to make sure. I said no and they sent the 4x100 so it would fit. :D Thanks guys! I am getting a new cat next month because I have the P-0420 code. I tried switching both O2 censors and still passed smog somehow, but going uphill, she slows down.

I have to say this is one of the better video on this subject.

[@glenncurley680]

Since new, I have a 2005 Civic SI with low mileage and was just informed that I need a catalytic converter. The check engine light has been on for 7 years, I paid the dealership to to do something, the first time I noticed it and replaced the gas cap. They informed me it may come back on and it did in about 3 days. For the last 4 years it never passes our E-test. Thanks for sharing, now I know what a catalytic converter is.

[@majorsay]

same mine need to pass ETest haven't yet

[@BloopsnBleeps]

Mine may be going bad on an 05 Civic and the price to do this is ridiculously expensive. So happy you showed me this. Not nearly worth the labor cost. Thank you for saving me hundreds.

[@luisl1817]

What were the symptoms?

[@Evan-hq5dt]

That's awesome, there is no other 7th gen civic cat replace videos online. You guys posted this 2 weeks before I replace mine today. Thanks a lot. Let's hope I can get those bolts undone, yours look a lot better than mine.

[@livingstonseagull2465]

because of 1aaAuto.com I've saved about 1000 dollars. These guys really help DIY everything on my 2001 honda civic. Just did a Front brake pad replacement and I'm thinking about changing the catalytic converter. I'm hoping I can figure out what's wrong with sensors but I replaced both. It's probably the intake sensor since it's flimsy and lose. It has a custom intake.

One of the best videos on the topic I’ve seen. Great work and thank you so much for this.

[@GG-cn6es]

Just a heads-up, only the D17A2 uses this style of catalytic converter. On the D17A1 the cat is integrated into the exhaust manifold.

[@artmac9181]

Seems like something I could do myself but when I took my Civic to my local auto shops they made it sound a little more complicated than it is. They told me they have to know the engine family number. After watching this video looks as if I can just order the part from you guys and make a switch. One shop even quoted me as high as $1500. As much as possible I don’t want to do it myself because I don’t want to get under my car on my back. But, with the price so high I may have to get on my back and just get dirty.

[@1AAuto]

+Arthur Maclang It's not that hard of a repair. Here is a link to the exhaust pipe shown in this video on our website. www.1aauto.com/2001-05-honda-civic-exhaust-pipe-with-catalytic-converter/i/1accd00320?KZbin&CTA+Comment&RdxbvRswQ

Are you able to connect to back off the Catilatic converter before you bolt up the front part, and does the car have to be jack up on all four wheels.

Hey 1AAUTO guys! Love your channel and you're always so helpful! I do have a question and I hope you can help. I'm planning on replacing my catalytic converter on my 2003 honda civic but I sadly can't identify if it is and LX or an EX and was wondering how big of a role that plays? Does it matter when buying a new catalytic converter to replace? Thank you!

[@1AAuto]

+Molly R Thanks for checking us out! Yes, it does appear the catalytic converter for the 2003 Honda Civic will be specific to the submodel.

[@krakenhits1587]

I have a 2012 Honda Civic LX and under the hood it looks like it complies to both Federal and California emissions can I use a regular catalytic converter or do I need to buy a California carb certified?

[@1AAuto]

+@krakenhits1587 If your vehicle states California then it would have California emissions. Thanks for checking us out!

[@AmericanThunder]

The replacement downpipe isn't mandrel bent the way the oem one was, with the crimped looking radius instead. It's a sign of a budget replacement part. Knowing that, the corrosion resistance of the replacement part is almost certainly nowhere near as good as the oem either. So if you live in a state that uses road salt, don't expect that downpipe to last very long.

[@MrAznRonin]

Thanks again 1A Auto parts! you guys saving me a ton from the Honda dealership. Plus, it help me get my car smogged regulated in CA. Btw, how many thousands of miles do you guys recommend changing both the down and upstream 02 Sensors? -Mr.NOS™

I'm about to replace my exhaust manifold but the one I'm getting, some people are saying, takes the cat converters place. Would I have to buy new exhaust piping or would i be able to keep the one i currently have(with catalytic converter). My inspections up next month and I'm getting po131,132,420 (my manifold is missing a bolt to the exhaust, and it rusted).

+MrDarfoot Thanks for watching! Certain vehicles have the converter built into the exhaust manifold, so it all depends on what you have. As for diagnosing your issue we recommend having a trusted mechanic take a look at your vehicle to get an accurate diagnosis. 1aauto.com

I have a question, I replaced my 2004 Civic DX engine with a 2005 HX engine. Everything is fine EXCEPT nobody NOBODY can tell me where to run/connect the other end of oxygen sensor from the underneath catalytic converter to where??? From the new underneath catalytic converter, I have a place to connect oxygen sensor on it... but where does the other end connects. Do I need to get a HX rear wiring harness? If so, where is it located? The local three Honda dealerships can't even tell me. HELP please. I just need to know where to connect the third oxygen sensor from the catalytic converter underneath the car that has had the engine changed from a DX to a HX.

I just got my cat cut off and stolen. Do you know how much it would cost for a 2003 honda element with 2 o2 sensors? Also, will i be able to pass smog with an aftermarket cat? Any warranties?

[@jnutz4871]

Well it depends on the new cat youre buying, different parts from different companies have different prices they can go anywhere between 150-600$ for a new aftermarket catalytic converter and if youre getting it done in a shop depending on the shop the prices vary due to cost of parts and also added labor so pricing out the process is kind of up to the shop unless you do it at home. Now if youre looking for a direct oem replacement rather than a high flow performance cat then yes it should pass smog no problem if you keep sure to get one thats legal for your state emmisions. Most aftermarket parts should list what states they can be used in and always double check before finalizing a purchase.

[@antthearchitect]

Is that first o2 censor the Bank 1 Sensor 2?

[@Dziricani]

That's bank 1 sensor 1 (upstream). Sensor 2 (downstream) is located in the middle of the catalytic converter itself.

+The Devil in Frankenstein If your vehicle resides in California, it needs to have a C.A.R.B. approved catalytic converter installed otherwise it will not pass inspection, and you may incur additional fines.

[@dramirez__]

Will the new catalytic converter make the car sound better?

[@1AAuto]

+DaveWave It depends on how yours has failed. If it's rusted through and has a hole in it, it's an open point in the exhaust system which can make the car sound very loud. So in that case replacing the cat. with a new one could close up your exhaust leak and make the car run more quietly. Hope this helps you out. 1aauto.com?KZbin&CTA%20Comment&ATony 866-403-3393

[@1AAuto]

+DaveWave I thought you might have meant from a performance point, but I wasn't sure. A high flow catalytic converter will definitely make the car somewhat louder, but if you were to combine it with an aftermarket resonator and muffler designed to allow for a loud exhaust you would have better luck. To properly tune your vehicles exhaust, however, you should look at where it all begins, the exhaust manifold. A custom exhaust manifold, with the proper muffler/resonator combo down the line, is where you will really find that throaty sound you're looking for.

[@1AAuto]

+Chavez I Thank you for checking us out. The code P0430 means that bank 2 catalyst system is not being monitored appropriately. Some possible causes are a faulty converter, intake air leaks, fuel injector leak or failure, faulty spark plugs or improper ignition timing. Usually diagnostic tools can be used to read live data from the fuel injectors and catalytic system for errors to pinpoint the issue. 1aauto.com
