Update 8/2020: 2.5 years later and <20,000 miles some dreaded P0420 the code is Returned. Substituting O2 Sensors (Dense Factory) and repairing 1 manifold broken stud has not maintained a code partorisca return. Everything signs point to a Cat. Any big shot or have thought like this. I have contacted MF Service of Client and on 10 days more have answered late and any one has guaranteeed this product. It is long more expensive of a competition and no better. Spent one $ 200 knockoff and have the tuner deletes a Backside O2s and will be $ $ $ advances in planting to buy these.

These are the substitution of the estimativa adds dipped of cats. As another has declared a metal of some pipes is thinner that factory and there is some noticeable exhaust noise resonating by means of a tubing in cold start up. I have not used a distributed gaskets; partorisca a the doughnut runs over has used Walker has recommended 31718 gasket in a side of engine and reused a bowl lateralmente of the passenger gasket how was a lot of and a distributed one of MF is not returned inside a manifold outlet. You will require the hog out of some holes with the step have bitten in yours that exists mid pipe with which some cats to ray on a new system to your cat partorisca exist-rear exhaust like MF studs is clocked the pocolas terracings out of a location of factory.

Would not have bought never these partorisca substitute the together of cats of working factory. My coverage of valve PCV was faulty and the oil has touched to an exhaust partorisca ruin some cats. If has the P4020 or 4030 code substitutes your coverage of valve with an up to date PCV! Otherwise Will ruin another together of cats!

MagnaFlow 93419 Conversor Catalytic Direct Record (Any CARB compliant)

Installation:
- 2002 GMC Yukon SLT w/ Flex Fuel.
- Total installs time roughly 2 1/2 hours.
- Dip a truck in ramps of Rhinoceros partorisca clearance, wheel added chocks.
- Date to endure a transmission with jack stand for behind a member of cross.
- Side of the passenger gone down of member of cross of the transmission partorisca extra clearance.
- Take all O2 sensors previously partorisca take a system partorisca exist.
- Used Milwaukee 2754 M18 Impact and PB Blaster partorisca take that it exists hardware.
- Has had to that use propane torch to loosen 3 dice of flange in the side of the engine.
- Reinstalled O2 I sensors afterwards install.

Pros:
- Apt was excellent.
- Has obtained mileage with which installation.
- Calm operation.
- To the same Quality likes OEM.
- Luz of engine of the control is not returned with which reset.

Gilipollas:
- Doughnut gasket Was slightly too wide to insert manually. It Finalising that it use of the originals gasket.

Recommendation: it would recommend this product.
5 / 5
A lot of
- Some cats are oriented so that it is easy to take to some rays of manifold (this has not been a chance with a Flowmaster equivalent)
- A O2 bungs is everything in of the convenient locations
- I in fact chooses on roughly 1 mpg after installing this and my line of the engine of the control has gone finally was, but this could be thanks to a new O2 the sensors more than an exhaust

Bad
- A lot the thinnest metal that stock marks an exhausts the noise that comes By means of an extremely strong metal, calm in fact can listens that it goes down a street.
- A rear flange does not line up with stock, is welded on in a corner. When Cold some leaks to cross, once covers one developed pliable focus of metal on 99.

Has has had to that he throughout again so only would take new cats welded to a pipe of factory, would have meant less screwing around with filtering cross and probably cost well on some same in a long career.

Has ordered for 04 Chevy Avalanche with 150k on that. The box has arrived promptly and wine with engine and passengers gaskets. It will require to order the box of cut of need of the ray have been, as I have done. The access was perfect. The subject only was on side of passenger. I pre-installed a O2 sensors but could not take a side of passenger to plant with a behind O2 the installed sensor, has has had to that the take, then situate a cat and pipe, then reinstall a O2 sensor.
Will require to pull a Tranny member of cross, any one hard, so only 5 rays. Commanded a tranny the support has disintegrated once a member of cross has fallen, has covered: $ . As it has to that cut all studs of old system, take the side of engine exhausts the leak, as it has substituted gasket, and reason could not take one 3 ray was has had to that exit, a work has taken 4 has been well to have a together extra of hands but has not been necessary. It does not remark any difference of his but already have the magnaflow muffler installed.
5 / 5
The access was perfect. Absolutely I add it it installs. It has had to that fall a side of a transmission crossmember (side of passenger) and a rest is the piece of cake. It was duly impressed with a record and wine with some necessary components to complete an installation with an exception, one 3 flat hole gasket in a side of engine exhausts interface of manifold. The $ 10 element. Highly it recommends this product of the costruttore highly considered. It could not be pleased more. There is remarked the profit of action also more probably because of a perfect mandrel has bent to pipe a the a lot of flowing creation of conversor catalytic. It gives it 6 stars could ! It does not have it drives far enough to verify a mileage but when an action augments that usually it means better gas mileage because of the minor throttle place without other transmissions.

So only installed this yesterday in mine 04 Silverado. I took roughly 4 hours. Some rays of manifold (15mm deep a lot of socket) all has required some heat and 1/2' ratchet with cheater bar to break some dice. A backside (where semence to a muffler) has not required hot, just ratchet with cheater bar. In the first place break all some free dice and then unplug a O2 sensors. Then sustain a transmission with the jack and some blockades of forests, take a member of the support of the transmission was. I have left a ray lateralmente of far engine in and the swung down. It takes some old cats, take a O2 the sensors am gone in a labour bank. Reassemble A O2 sensors in some new cats, and turn some together sections for one install and slide a clamp on but of the that presiona still. Returned the all behind down a truck and you am good to go. A rear connection to a muffler was bondadoso of the ache in an ass, but took it there. Claro a code with the scanner of code and are P0420 code now. It will update if these transmissions. Although it would substitute my O2 first sensors to allege this assembly of the cat is not doing.
5 / 5
Installed on 03 GMC Yukon XL 5.3. Other state descriptions to take member of cross of the transmission - ossia true. It does not try another way to take an old or install a new. I have tried different ways to do work without doing this and has taken the plot more time that has had has takes so only one 3 of some 4 rays and some 2 dice in a trace of transmission. I have had question with 1 of the mine O2 sensors and has had to that substitute concealed but after a tranny the member of cross was out of a way all is gone in smoothly. There is remarked the little deeper noise of that was fresh. Direct access. Any instruction but the common sense have helped to install everything.

Direct access? Not even near! I have had to that modify a boss to exist pipe and a pipe of conversor to take a pipe of conversor to return a frame of a truck, is almost likes is exited of his way when I draw this for the do ALMOST RETURNED
has been a automotive technical for twenty years and facts in the impulse and has had to that heat and bend several places to take he to plant, then rib a factory to exist pipe that has to that and for behind a conversor to do this work, although once it was in a truck is spent of the emissions he so that it was more economic that a course of factory, unless you owe that it pays for the have put in then buy a factory gm the part will save money because of WAY. The labour costs lower, can take a truck in an air, is ina tent with all some tools and dollars of trade of the torch to do

has Purchased this for mine 2002 Tahoe with 200,000 miles with which fully troubleshooting some have dreaded P0420 code to a side of engine conversor catalytic. It looked in of the numerous products but this one has won out of both the name and perspective of quality. More, is two unit of piece and felt that an installation would be easier. In fact, an installation was quite easy and have fallen yes a support of transmission to relieve installation. I took roughly 4 hours to install - which has comprised scrolling of some old pipes and an installation of this box. Calm does not need the second pair of the hands likes them declared in of a estaca sooner. A quality of this box is point and averts. As declared in an earlier description a welds is cleaned and some pipes and the flanges are fat and any warp. With which move of an old system there is remarked the species craps to exit of a pipe lateralmente of the engine - I assumes of a conversor. I have cleared a P0420 the code and there is not going back. There is remarked the light increase in an end under the torsion and an exhausts the notes is quell'has bitten deeper/loader. Highly it recommends this box. Calm can not beat a cost and quality.
4 / 5
The product has been rid in just the few days. A prize was $ 200 less than other retailers and means that some quoted tents. The installation defied but -able. A part is returned as it has to that with all gaskets and clamp has distributed. A lot happy with a result and I have saved in $ 700 the doing I.
Notes - before a light of the engine of the control is coming on has had the strong rattling the noise that comes from/comes from a side a low plus accident of an engine. A noise was an element of interior of a conversor catalytic that pauses on and that paste an enclosure of metal. Good regime !

Does not love so only to say work without giving details, but could be hard as it has not measured or aims of data to present.

Will try to say long history the scarce, and can see like this is doing.

2005 Deep Pilot, on 190k miles.

Late 2019, a light of the engine of the control is coming on for a first time while I am driving and has been was before it could spent the to a tent to verify. I mentioned it to a mechanic when spent my car to do interview, verified it and has said one was conversor catalytic and asked the attention of paralización only, and probably any need to do a lot of control or fix punctual. A light has gone back on and then was perhaps the handful of time, but is remained was for a plus. A car is spent an inspection of emission in an end of 2019 without any question.

2020, Because of Covid and work of house partorisca in new month out of a year, has not driven a car a lot a whole year, probably roughly 300 miles the month(used to be - miles the month). A light of the engine of the control is coming on and was resulted worse and worse. I have bought the reader of code and verified it, is P420. I have continued to speak with my mechanic has continued to say the probably any value an endeavour and money to diagnose and fix, and can spend an emission, would have to be good. For an end of a year, has driven with a light of engine of the control on around 80 to 90 of a time. A light has been he was once the moment but he would go back on shortly. A car is spent a test of emission again in December.

While it speaks in a light of engine of the control with a gentleman the one who has run a test of emission, said that it could it to it have some more cleaned can use to see could correct a subject. Cela Direct to buy this. During a prime minister bounces with roughly 16 chevron of gas, a light of the engine of the control has been he was with which roughly 50 miles to drive, is remained was for roughly 80 miles, has then come on again and is remained on for another 60 or 70 miles, then was and on again a lot around time a tank was to look for empty (240 miles).

Has taken another tank of gas without a cleaner, roughly 30 miles later, a light has been he was, and now have roughly 150 miles with this tank of gas is it remained was.

My conclusion is that it is very clear, these cleaner works. I plan to take the pocola calms more bounced and continue use it until an engine to control the light stays was paralizaciones well.

Has been impacted after dipping a material in my tank a light of engine has been he was immediately after beginning a car. It has done. I didnt the attended concealed! If I have read this in the description, would not have believed it. It would have thought that it that it was another description of fake. But so only I write the sincere descriptions and I can be very critical.

Likes that it was easy to use and work. Has the 2005 TSX with 175k miles. An engine of light infamous control P0420 (bad cat) is coming on the pair in fact month. After confirming that mine O2 the sensors were less bad, has tried additives of use in the first place first to spend $ 1k in the new cat. Have in the first place used a Techron cleansing of system of the fuel, reset a one thousand and he have gone back after driving for the pair of days. As it looked around for the cleaner of cat and found this product. They are so only in the 1/4 tank (100 miles) and a one thousand already has turned went by. Still I have 3/4 tank to go I so that it will update my description goes back . Also my better car walks now. I guess the cat of clog affects action of engine.

This produces a lot anything to clear a CEL code in mine Subaru has bequeathed, but imagines them a cat is probably so only has broken. I think the enormous distinction to do here is yes or no your conversor catalytic is in fact clogged/soiled or has broken... More probably all the world-wide saying this has not done for them probably precise the conversor catalytic new. Felizmente For me, the any one precise to spend tests of emissions because my car is the 2006 . Potential buyers, so only maintain that in alcohols. I can not say work but neither will seat here and say he no, neither.
