Do you have to completely eliminate the factory cat's in order to install these? And if so does anyone know a good way to either have your system remapped so as to keep the check engine light off and maintain the vehicles ability to monitor the fuel...

Yes, factory cat's will come out with the factory headers...I ran custom 3" piping to muffler and got rid of check engine light with custom tune...

I wish I had an answer for you. All I can tell you is that their cat converters are not good. It did nothing but set off my check engine light. The only cure was to replace it with a GM original equipment converter to eliminate the problem. I forced Magnaflow to pay for it including labor at a local repair shop.

Mine are gathering dust in the glove box as well. I searched for awhile and gave up. I figured they might have been an interior upgrade option I didn't have. If you find it please post it lol.

No they did not. The installation was supposed to be possibly below counter/ console/ car dash using what came with the car and / or what ever it is being installed in. That's what I was told at the time; so I used them anyway.

Did you disconnect the battery as instructed to help the ecu reset after installation? I had a slight drop as well and you may need to install a less restrictive exhaust as well. I went with a Magnaflow system. It helped with the sound and the mileage.

Just install the factory tune before you bring it in and there is no cause for concern. Depending on the dealer you could just leave the tune in. Some will have a hissy fit, some won't. All depends on your local dealer.

Good question. I checked around the web and couldn't find any info. Check the back of your owner's manual; should be there. Otherwise call dealer parts desk and ask them.

Yes, And my exhaust is sounding nice & my gas mileage is WAAAAAY better. I also replaced all 4 O2 sensors after the install. But it was well worth it to get this cat back system. You won't be disappointed

I have an F150 with the 5.4 engine that is positioned longitudinally, so my cylinder banks are oriented right and left. The o2 sensor on the engine side of the cat is #1 and the sensor downstream of the cat is #2. I recommend you go to the Bosch Auto Parts web site and look up your vehicle. It specified this sensor for all 4 locations on my vehicle. Yours may require different length electrical connections (wires) to connect to the #1 vs #2 cat.

No these have to much spark for the engine and the computer will reconize and try to adjust. It will not run good. Use factory equivalent only. You will save time and money.

Well there's lots of tips if read around on how to get them adjusted. I just took the old box away and put the car genie in the same spot my other box was in. My cat took to it right away. However you switch them over depending on your cats behavior. I did the cold turkey method. Rather risky. Lol

Only Honda can answer that, and they, of course will say "yes" why would they say anything else. The point is that it is easy to swap the old one back and then how would Honda know? I completely disagree with the other poster. this device substantially improves performance both subjective and on the dyno. Changing out the "cat back" is a serious change that is certainly not within warranty. I would NOT do that.

hello I live in Kazakhstan, but I have an address in the United States for shipments. My car is 2004 Ford Explorer Sport XLT 4.0L V6. Can your programmer to disable such systems as "EGR", "EVAP" and catalyst oxygen sensors without installation pre-installed firmware?How can I learn more about the pre-installed firmware?

Jon, let me clarify. I was able to turn the check engine icon off in my 07sts. the (minor) problem may still exist in some form but i was able to turn the light off which is all I wanted for my used car with 120k miles. The scanner allows you to check what the code is decipher it (with cheatsheet) and elect to turn it off or not. I hope this helps. GSJ

No..... They work Great..... If you want to improve your mileage and horsepower you can do the fuel pack and other things that will cost you about a thousand dollars... Not including the Labor...but you don't have to do that..... I was told the same thing but didn't know better.... I wish I would have put these on a long time ago.....

Sensor 1 is bad. It's possible sensor 2 is as well but I would start with just sensor 1 because it could be reading "unknown" because the lack of a signal/data from sensor 1. You didn't specify if they were upsteam sensors (O2S11 & O2S12) or downstream after Cat (O2S21 & O2S22), but the upstream sensors are the most important cuz they control fuel trims & Air/Fuel Ratios. The downstream sensor are really only there to tell you if the Cat is good or not. I'm assuming you only have one Upstream & 1 Downstream sensor but some vehicles have more depending on exhaust setup. You may only see O2S11(Upstream 1) & O2S21(Downstream 1) or a combo of O2S11(Upstream 1), O2S12(Upstream 2) & 02S21(Downstream 1). Or even two Downstreams if you have true dual exhaust & not a Y-Pipe. You can tell if it's a upsteam or downstream sensor by the 4th character in the name coding. Example: 02S*1 * = 1:Upsteam, 2:Downstream. You can tell if it's a right or left sensor by the 5th character in the name coding. Example: 02S1* * = 1:one side, 2: other side. (Sorry can remember which one's right & which is left) Hope this helps.

Chances of Ford dealership having a Fortin Flash-Link Updater module (required to update Fortin Evo-All module and set options) are slim to none - dealerships prefer to install overpriced "Original" modules. I can program this module for your specific car remote dot start at yahoo dot come
