🔥 Dorman 674 933 Integrated Catalytic Converter: Optimal Performance, Durability, and Hassle-Free Installation Review

Everything came quickly and is handed over packaged. Tons saved compared to dealer. Installed perfectly (husband not me) and works great.

Only lasted 6 months at 3000 miles. The customer came back with the same code P0420 (catalytic system efficiency below threshold). Revine promised to send a replacement. Hope this works fine. I don't know if Dorman reimburses labor like other catalyst manufacturers (Catco, Walker).

The manifold and catalytic converter worked fine for 18 months. The catalytic converter is giving my Nissan Altima an error code and is losing power. Dorman didn't help and said I needed to file a lawsuit with Amazon. Removal/replacement is $1,000. Revain only offered me a $150 loan if I didn't send them a collector.

I bought this part for my 2010 Altima. fits like a glove no longer smells of exhaust fumes when I turn on the heater. Before I bought this part I shopped at various places like Auto Zone and Advanced Auto Parts, they wanted about $440 for the part so it was great to find it at Revain for $302! By the way, don't go to Mr. Tear's on Joppa Road in Baltimore, Maryland, they tried to charge me $1000 😂😂😂 I paid $550 for the part and install, thanks Revain 💯👍🏾

This product failed after being installed in my car for a little over a year. I paid for the fitment once, now I have to pay my mechanic again to replace it and the warranty didn't want to cover the fitment. returns department. said: "Application for reimbursement of installation costs involves a lot of paperwork, hassle and extra steps. Better get a part right away." Well now I have a part and I need to pay my mechanic a second time. Talk about customer service and part quality. I would give…

Great alternative to OEM, also approx. 50% cheaper than OEM. Do-it-yourself exhaust manifold replacement on a 2010 Altima will save you a lot of money compared to going to the dealer. Be prepared to spend half a day at the stock market. The belt and alternator must be removed to access the lower right manifold bolt. Spray liberally with WD40 or PB Blaster to remove any stuck screws. On a difficulty scale of 1 to 10, where 1 means an oil change, that's probably a 3. Basic tools required, a 10mm…

UPDATE NOVEMBER 2018 and the part needs to be replaced again. Although I can't complain. Worked great for the price. I'll probably try a different brand. I used this on my 2007 Nissan Altima. The original cracked at the converter. I examined the original and couldn't find a crack, so I installed the original with new gaskets. I still had a leak. I found and ordered this one because I was pretty sure the distributor was the problem. I also ordered http://www.amazon.com/Walker-54782-Direct-Catalyt…
