Modern Performance has stepped up for the Dart community once again and produced an absolutely beautiful 4-to-1 header with catalytic converter for the 2013+ Dart 2.0L / 2.4L. This header bolts up to your factory or aftermarket exhaust system without any custom modifications. It is made of high quality mild steel, and is MIG welded by hand.

MPx Header & OEM Header Comparison 2.4 Dart OEM header/cat unit
Overall, the OEM header is not a bad looking piece, but the primaries could be smoother, and we surely didn't need a catalytic converter that was almost 20 inches long. There was a lot of room for improvement!

Exhaust gas keeps a high velocity when it doesn't encounter sharp bends and restrictive catalytic convertors like the one found on the OEM header.

The MPx Header produces up to 11 HP and 12 ft-lbs of torque at the wheels. Power is gained across the board with its beautifully smooth equal length primaries and its high flow cat. Please view our dyno charts in the photo section to see the gains across the board. There is no loss of power or torque with this header.

Most importantly, you should not get any check engine lights with this header. If you do happen to get a CEL, simply get in touch with us for a quick and easy solution.

This header is offered in two options:

  • Raw Steel - Ideal for customers on a budget, or those of you who intend to do your own coating or wrapping.
  • Ceramic Coating - Looks great and thermally insulates to keep under hood temps cooler. Also has a thermal barrier on the inside of the primaries. Ceramic coatings are meant to be left open, do not use any wrapping products on ceramic coatings.

This kit includes:

  • Upper header
  • Lower B pipe with catalytic converter
  • o2 sensor extension harness (because the downstream sensor is moved further down)
  • Header gasket
  • Clamp to secure the B pipe with cat to the upper header outlet.
  • Zip tie to secure extension harness
  • Bolts to secure exhaust to the B pipe outlet
  • Notes:

  • This header has a factory style outlet flange so it can bolt up to the stock exhaust, or any aftermarket exhaust designed for the Dart. Please read the notes below about connecting to this header to a factory exhaust.>/li>
  • This header package replaces all of the factory components from the head all the way back to the exhaust B pipe flange. Nothing else is needed.
  • You can read the many reviews on this part from other Dart owners by clicking on the Read or Write Review link on top of this page under the title next to the gold stars. This is one review posted by Walter B: Bought the ceramic header for my 2016 Dart 2.0 and it not only looks great but has made a nice difference in performance. I have all the power-adder components available installed on my car and the difference in performance from Stock is very noticeable.

    Check out this customers video he made of the install of this Dart header onto his Chrysler 200 with 2.4 engine.

    IMPORTANT
    This is a high flowing, performance header. Its designed to increase power and torque. The OEM catalytic converter that is on your Dart from the factory is like a huge muffler, and therefore drastically reduces the sound level, and raspiness of the exhaust note. Therefore, when we use a high flow catalytic converter on this header, after you install this header, the sound level will increase and there will be a raspy tone to your exhaust note afterwards. If you are ok with a louder and raspy tone, thats fine. If you want a quiet exhaust note after installing this header you will need to add additional mufflers or resonators to quieten down the sound and tone. You can install mufflers on your B pipe of your exhaust, or near the exhaust tips near the back muffler. A good local muffler shop or mechanic should be able to help with this if you want to reduce the sound/tone. Or you can use the MPx Dual Exit exhaust with mufflers that we designed from scratch to use with this header.

    Important Note 2: If, after installation you ever check a check engine light related to the catalytic converter, please contact us by email to discuss. We can help troubleshoot by email and have many years of working with this header system. Please include the check engine code from your obd2 scanner if you have it.

    NOTE3: This header kit is shipped in two boxes, one for the header, gasket, hardware and the other box is for the downpipe with catalytic convertor.

    • Brett A.
      What are the specs on the piping, primaries and the down pipe? And does it neck down at the flange to bolt to stock exhaust?
      1 Answer
      • customer service rep

        The primaries are 1.8 od, collector outlet is 2.5 od, outlet of downpipe to factory b pipe is 2.25 ID.
    • Mike
      Have you tested this header with the 2.0L? Does this header plus the flowmaster exhaust lose too much back pressure, causing a negative change in performance?
      1 Answer
      • customer service rep

        The only way you'll lose power, is if you go with too large of a diameter of exhaust. In testing, we have found 2.25 to be the best diameter for the 2.0/2.4. Going to a 2.5 helps for a small range of top end power, but creates more loss in lower end and mid range.
    • Andrew
      Does this header paired with the stock exhaust create a raspy sound? if so what after-market exhaust would you suggest.
      1 Answer
      • customer service rep

        Because of the high flow cat flowing so much better, and not acting like a muffler like the oem cat, sound levels will increase. You can easily add two small resonators on the rear of your exhaust to make it much quieter.
    • Brad
      Does this void my factory or extended warranty?
      1 Answer
      • customer service rep

        This part should not give you any problems with the dealership.

        The only thing that might be affected by installing this warranty wise would be the exhaust manifold gasket, and or possibly exhaust related issues.
    • Adam
      Will this new header be able to pass smog in California?
      1 Answer
      • customer service rep

        (This question only applies to Dart owners in California where there is strict CARB testing) It would pass in every other state with inspections. This header is not carb approved. So, you can use it in California, but at time for testing if you do a carb test, it would not pass the visual inspection.
    • John
      To get the performance gains with this header, will I also have to install a performance exhaust system? Or, can I keep my factory installed dual exhuast?
      1 Answer
      • customer service rep

        Regardless of which exhaust you have, you'll gain power over the stock header with this.
    • Sean
      Will this header still have a catalytic converter? Concerned that if I install this I will not be able to pass the emissions in my state of TX.
      1 Answer
      • customer service rep

        Yes, just like it states in the title of the item, this header has a catalytic convertor.
    • Sean
      Noticed that there is a sensor on the OEM header, will this one have/use the existing sensor?
      1 Answer
      • customer service rep

        Yes, this header will reuse the existing upstream and downstream factory oem oxygen sensors.
    • Trevor
      Can you paint over the ceramic coating?
      1 Answer
      • customer service rep

        We do not recommend painting anything over the ceramic coating, its best to leave the coating the way it is.
    • Jeremy S
      Will this pass emissions testing in Massachusetts?
      1 Answer
      • customer service rep

        This header will not have any check engine light, and there will be no problems emissions wise for any of the 49 states in the USA. Only California users will have problems as they have stricter CARB emissions testing there.
    • Donald Mil
      I am in need of another gasket as I re wrapped my primaries, will the oem gasket from dealer work or can I order one from you?
      1 Answer
      • Customer Service Rep

        You can use a OEM Chrysler gasket with this header if you ever need a replacement.
    • Chris
      I know a lot of parts are interchangeable with darts and chrysler 200s that have the 2.4l... will this fit?
      1 Answer
      • Customer Service Rep

        The upper piece of the header will bolt to all 2.4's in the Chrysler 200/Renegade, etc, however, the lower piece has a mounting bracket that will need to be modified, and sometimes extra piping needs to be added to extend the flange to different locations. Also we have found other Chrysler models with mass air flow sensors after the airbox to be problematic with catalytic convertor monitoring, ie, they trip the check engine light easily due to the high flow cat.
    • Neal
      Hello will this work with a 2014 2.4l limited with single exhaust
      1 Answer
      • Customer Service Rep

        Yes, this fits with all exhausts for the Dart, single tip exhausts, no tip exhausts, dual tip exhausts, Flowmaster, MPx, Magnaflow, Heartthrob, etc.
        As long as your exhaust bolts up to the factory style 2 bolt flange on the factory header, then it will work fine with this header.
    • Jason Childers
      How hard is the installation should it be done by a muffler shop?
      1 Answer
      • Customer Service Rep

        Any good mechanic shop or muffler shop could easily install this header.
    • Josh M
      What is the inlet and outlet diameter of the cat converter on this?
      1 Answer
      • Customer Service Rep

        We use a high flow 2.5 inch inlet and outlet catalytic convertor.

    • Leo Perl
      so why do you say that the dodge dart dynode at 154 when it's advertised that the dodge dart makes 160 hp stock
      1 Answer
      • Customer Service Rep

        What a manufacturer claims a car has horsepower wise, and what is at the wheels horsepower wise are two different things. Dodge says, 160 hp for the 2.0 engine, but whats at the wheels is more like 135 or 138 horsepower because by the time the power goes from the engine, through the transmission, through the axles, through the hub and bearing, to the wheels, to the tires, you lose power. Typically from 10-20 power loss from the engine to the tires. Manuals have less power loss, automatics have more power loss.
    • Christian Rodriguez
      I recently had my 2.4l dart straight piped. Would this be a problem in the future when I purchase this to be installed? Could I use existing straight pipe when installing this product?
      1 Answer
      • Customer Service Rep

        You can do whatever you want exhaust wise, but like we mentioned earlier in the Q&A, we highly recommend you add two mufflers or resonators on the exhaust to quieten your exhaust down after adding headers, if you have zero mufflers or resonators its going to be very loud and raspy, not a good combination.
    • Trevor W.
      I was curious about the ceramic coating option. Is it the typical white color, or do you offer a variety of color options?
      1 Answer
      • Customer Service Rep

        Look through the photos to see the finishes - the raw steel looking header is the raw finish. The high luster, chrome header is the chrome header, and the dull silver finish is the ceramic finish. Those are all the options.
    • Joey
      Do these headers come with a gasket?
      1 Answer
      • Customer Service Rep

        If you are asking about the gasket between the header and cylinder head, yes we provide that gasket, you can see it in the product photos. We do not provide a gasket between the two bolt flange and your exhaust.
    • Kevin
      Do the headers have any fit issues with the factory engine cover? I noticed in the pictures that it was removed.
      1 Answer
      • Customer Service Rep

        No, not at all, we are just not fans of the plastic cover. You can use the header with or without the cover, whatever you prefer.

      Interested in purchasing, just wondering if this can be installed on a 2013 Dart 2.0 automatic trans or only a manual?
      1 Answer
      • Customer Service Rep

        This header works on all 2013-2016 Dodge Darts with 2.0 and 2.4 engines. Works fine with automatic or manual transmission.
    • Umar Rasool
      Will this fit on a 2.4l renegade?
      1 Answer
      • Customer Service Rep

        We have actually made a MPx header for the Renegade with 2.4, look for it in our Renegade section. For other Chrysler 2.4 vehicles, the upper piece of the header will bolt to all 2.4's in the Dodge Promaster, Fiat 500X, Chrysler 200, etc, however, the lower piece has a mounting bracket that will need to be modified, and sometimes extra piping needs to be added to extend the flange to different locations. Also we have found other Chrysler models with mass air flow sensors after the airbox to be problematic with catalytic convertor monitoring, ie, they trip the check engine light easily due to the high flow cat.
    • Josh L.
      In you guys' experience, how much of a difference does the ceramic coating affect the longevity of the headers vs the chrome? I really like the look of the chrome, but I am trying to decide is the ceramic is really with the extra $$.
      1 Answer
      • Customer Service Rep

        The ceramic coating is applied on the outside and inside of the header, and does a fantastic job of eliminating heat in the engine bay from the header. The ceramic coating will last a long time, possibly the same length of time as the chrome, or even longer. The chrome coating looks good but does not keep the heat in the header like the ceramic coating.
    • David Johnson
      The header as far as I can tell has only 1 o2 sensor port. The problem is that it looks like my Chrysler 200 (2.4l tigershark) has 2. Have you found a way around this or do I need to delete and o2 sensor?
      1 Answer
      • Customer Service Rep

        This header has two ports, an upstream and downstream exactly like the factory header. Check out the various photos we have, and you'll see one port behind the cat to monitor the cats efficiency, and another port on the driver side area of the collector where the four primaries merge. Your factory o2 sensors plug into the top with no issues, and you use our included o2 extension harness for the downstream o2 sensor port.
    • Nate
      Hello, I was looking in some forums and found that alot of people were wondering about torque specs of the bolts. I was wondering are there install instructions for people that want to install this at home? If not is there any place that i can goto to find these answers? Thank you and have a nice day.
      1 Answer
      • Customer Service Rep

        38 ft lbs is the torque required on the bolts for the 2.0 and 2.4 Dodge Dart header bolts.
    • Cameron White
      I am really interested in this header, but want to know if it will fit nicely with the Summit Racing cat-back I have?
      1 Answer
      • Customer Service Rep

        Whatever exhaust you have, it does not matter as long as it connects to the factory header.
        If your exhaust does not require the factory header flange to be modified, and you installed your new exhaust with the factory header, then this is going to work fine.
    • Rell
      So it adds 11hp? And also I noticed in the side by side comparison picture the stock has a hole and custom doesn't why is that?
      1 Answer
      • Customer Service Rep

        Yes, 11hp as it says in the product text, and shown on the dyno charts in the photo section.

        The upstream 02 sensor location is still on this header, just as the factory header, but is moved to the side of one of the header primaries.
    • JT Hierling
      I was wondering if I got the raw steel, could I paint it with high temperature paint and then wrap it? I want this product but I don't want to spend 120 extra dollars. I know you're not supposed to paint over the ceramic coating but nobody asked about the raw steel
      1 Answer
      • Customer Service Rep

        Correct, ceramic coated headers should be left open, and not wrapped. If you bought a raw header you could paint it and wrap it as you wish though, yes.
    • Gage Calabretta
      Interested in buying but was wondering if the Dyno results shown we're an automatic or manual?
      1 Answer
      • Customer Service Rep

        The dyno results we showed were from testing on a 2014 Dart GT manual with 2.4. Automatic 2.0/2.4's will still gain power, but because automatic cars usually have less power at the wheels then manual cars, you'll have less of a gain compared to manual transmission cars, but still a gain over the stock power levels.
    • Brian Sliwinski
      Is modern performance planning on making a header that is carb legal living in cali is great except for vehicle mods but i would really love a high flow header but i want to keep it legal
      1 Answer
      • Customer Service Rep

        No definitely not. It is cost prohibitive for aftermarket companies to undergo CARB testing just for products to be sold legally within California. We have heard it costs tens of thousands of dollars for the testing, and that is why almost no products other than air intakes from K&N and AEM are CARB tested, and approved.
    • Liam Dale
      Do I need a tune for this header kit after installation I have a 2016 dodge dart sxt with a summit racing catback exhaust installed already.
      1 Answer
      • Customer Service Rep

        No tune is needed. The Dart uses a map sensor, which automatically adapts to improvements in air flow/engine performance. So you can install a header, exhaust, intake, etc on the car and it will make more power immediately with the stock ecu tune.
    • neal
      hello will this part effect my air to fuel ratio on my dart
      1 Answer
      • Customer Service Rep

        Your car's air fuel ratio is determined by the ecu, map sensors and air intake. The exhaust system and header will not change the air fuel ratio, it only allows the exhaust to flow more easily.
    • Gilbert Sanchez
      What happened to the chrome finish option? I want some blueing color on the header after using it. Can you paint it chrome if I order?
      1 Answer
      • Customer Service Rep

        We discontinued the chrome finish in late 2023. You could buy the raw header, then prep it, and chrome it yourself or have a coatings place coat it to your desired finish.
    • David
      Is there a difference in sound or performance between the three options of the raw steel,chrome plated and the ceramic coated one???
      1 Answer
      • Customer Service Rep

        Its possible the ceramic coated header might be a little quieter, maybe 1-3 decibels, due to its coating on the inside and outside of the header compared to the other headers raw or just chrome exterior coatings.
