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

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 socket, 12-16mm sockets, 21mm sockets for the wheel, a torque wrench and a crowbar. A hammer will come in handy because. The heat shield didn't go all the way up. A few bumps on the aluminum heat shield and it fits perfectly. UPDATE 4/11/18: It's been a little over 3 years and the catalytic converter failed and got clogged somehow. The dealer investigated and found the problem but was charged over $1,000 for a replacement. If I knew this product would only last 3 years I would buy cheap $90 collectibles on eBay I'm sure they would last just as long. From what I've read about Dorman products there might be a 5 year warranty for 50,000 so I'll investigate further.
