      I used this on my 2007 Nissan Altima. The original one cracked on the converter. I inspected the original on and could not find a crack so I put the original back on with new gaskets. I still had the leak. I found this one and ordered because I was fairly certain that the manifold was the problem. I also ordered the http://www.AutoPartsWAY.com/Walker-54782-Direct-Catalytic-Converter/dp/B008RYMT28/ref=sr_1_1?s=automotive&ie=UTF8&qid=1425323187&sr=1-1&keywords=Walker+54782+Ultra+Direct+Fit+Catalytic+ConverterI bought both not knowing which one would be the issue, but it was still cheaper than taking it to the shop. The Dorman Manifold fit without any issues. The heat shield took a little working with as the bolt holes did not line up perfectly. The heat shield is thin and easy to work with. Total time was maybe 3 hours.Also, I am a fairly experienced mechanic and have had nightmare stories about working with exhaust systems. I live in the South so no salt on the roads help. I did...

      It is awesome. I got it almost 2 weeks ago and Assembling was very easy to me. You need to remove 13 screws for catalytic converter. And 3 more for cover of converter then you can implement it easily.

      Working great, bolted right in, heat shield went back on, but most importantly, it passed the emissions test!Now has 1.5 months driving on it, solved the check engine light code P0421, and is working great.

      Great Deal. Fits like a glove. Included everything, all the nuts, bolts and gaskets that were needed to do the job with out a trip to the auto parts store! If you have a Toyota RAV4 and have codes P0420 Catalyst Efficiency Below Threshold Bank 1, P0430 Bank 2, this is your fix.

      I bought the kit to replace a bad cataytic converter in our 2004 Toyota Camry ES with a I4 engine. The replacement manifold fit perfectly to each end of the exhaust; however, the old heat shield had to be slightly modified in order to attach correctly to it. Basically I had to drill a new hole in the heat shield. The only other issue I had is that the replacement "kit" did not come with new studs and the old ones were unusable. I called directly to Dorman and they appologized and overnighted me the new studs and nuts. Others have remarked that their kit did not include the studs either and Dorman is working to correct this issue. This is a quality unit and I think well worth the price. For the 04 Camry, be prepared to make a small modification in the heat shield and if your unit comes without studs, just give Dorman a call. Overall very pleased, especially with Dorman customer service.

      The Price is Awesome, The fit is OK. They need to include 02 sensor plug for post cat! My post cat 02 sensor is located down under the car not 4 inches away from pre cat so i had to run to the automotive store and locate and buy a plug (big hassle could've been avoided). The factory heat shield holes needed to be enlarged do to brackets being welded incorrectly and mounting holes are quite large to accommodate it not being exact fit, BUT overall nice product, good price, that it has all the bolts and gaskets included!

      Pretty good aftermarket replacement. Fit fine and runs fine, if a bit stinky for a couple of days until the coating burns off. A few details make it short of 5 stars. No instructions is the biggest issue, though I did manage to find enough on the web to figure it out. Doesn't come with all the studs you need to do the job, you have to re-use the original ones by pulling them off the old manifold, which requires a special tool that's not widely available. New exhaust hanger bolt that does come with it is different than the OEM but it does work.

      Bought it for my 2006 Tacoma 4.0 trying to get it to pass smog in California. As some of you know, if it isn't stock, it probably won't pass in California due to the retarded CARB restrictions. Nevertheless the dealer wanted $1000 to replace it, and I found this for around $300, gambled on it passing and put it on myself. It saved me 700 bucks because it not only looked identical to the factory unit, it passed without issue. Even if you aren't in Cali, it's a deal since it's such an easy job. Fully recommend this product!UPDATE: about 7 months (5k or so) after putting it on, I developed a HUGE exhaust leak....needless to say, one of the welds holding on the heat shield busted and ripped a 3/8 inch hole in my manifold....will try and repair. Not sure if it would be a common problem though, as I can't see it doing that every time a tiny spot weld comes loose.

      Installed on a 2003 Mazda 6 3.0 V6. As advertised it was a direct fit replacement and is working fine. Included manifold and exhaust gasket as well as new bolts for the exhaust. While it was a direct fit the welded on heat shield was not exact and took extra effort to reinstall the bolts on the head. I installed new upstream and downstream O2 sensors at the same time. Price on AutoPartsWAY saved me huge $$$ over OEM and local auto parts stores. Any changes I'll post an update.

      From my husband: This same exact part in my local auto parts store was over $500 more than what I paid for it here! Bolted up perfectly and works exactly as it should!

      I boutht these to replace the OEM Nissan exhaust mainifolds that were cracked. The fit and finsh seems pretty good and they bolted right up like they're supposed to. I'm hoping that these won't crack like the OEM junk.

      Awesome. lifetime warranty on a converter! I am a certified repair shop and this is the exact product AZ sells for 519.99 carquest 492.83. unbeatable price. This is the same company that sell almost all window regulators to the aftermarket. Product was a perfect fit too.

      This will need a little help on fitting the heat shield as most everyone has noted.Just plan from the start to have a drill and enlarge the holes on the shield.Have a persuader (rubber hammer) handy to shape the shields a bit.Take care to try and keep the old shield fasteners. I found the old ones were better in some locations than the new ones that come with this kit (a little longer).I also slotted the first hole to avoid removing the alternator. You'll understand and see this advantage when you get there. The original came off without removing the alternator.

      I was looking for a replace cat. I decided on this one. the cast iron exhaust manifold is just like OEM. And will out-last any tubular unit. Thick steel exhaust flange. Includes heat shield as pictured. Also includes all gaskets and hardware. It was a bit more than the pacesetter unit, but Dorman products have never disappointed me. Good warranty. Even though it was a bit more, it was still cheaper buying it on AutoPartsWAY.

      It was nice to work with something made in the USA that showed good quality of construction. It performed flawlessly.

      Easy to install, just had to remove A/C compressor. NOx and CO is lower than last year with the OE cat. Fitment is exactly the same as the old part. Appears to be high quality.Make sure you use new mounting nuts and studs, and that you oil them before installing. The cat comes with new bolts for the y-pipe. I also installed new denso oxygen sensors and ignition coils/plugs. I also replaced the rear cat but that's a different review (dorman 674-830) planning an aftermarket sports exhaust soon (magnaflow borla etc) the sound with these and the oe muffler is good. Seems more rumbly than before but I drove it partially clogged for a while, my memory my be hazy.

      I replaced both sides of my exhaust headers with Dorman Aftermarkets, and it solved my issues and improved gas mileage by about 3mpg. It is a big job, but these kits are complete and well made, and about 1/3 the price of Nissan OEM and about 1/2 proce from AutoZone Dorman same exact parts!

      Great price, quick shipping. When installing had to use a ratchet straps to pull the pipes into alignment with opposite side. Engine light is now out... so VERY happy. Saved BIG $$$

      the exhaust manifold had to bungs for O2 sensors, my car came equipped with 1, I had to find a plug to fit the hole did not come with kit, the heat shields did not fit properly had to make fit re-drilling mounting holes, that should come ready for installation instead of having to search for plugs for O2 hole,
