(Discontinued) MPx Header w/ Converter Pipe, 2015+ Renegade 2.4L/2018+ Compass 2.4L

(Discontinued) MPx Header w/ Converter Pipe, 2015+ Renegade 2.4L/2018+ Compass 2.4L

This product is now discontinued, we have no more left, sorry! You can buy the upper header section, gasket, and o2 extension harness from us and work with a local muffler shop to make a downpipe for your car to make your own header system. Click on this text to jump to our replacement header parts page to see more information and pricing.

Below is our old product text

We first released a header for the 2.0L & 2.4L Dodge Dart back in 2014, and we have now produced a header with high flow catalytic converter for the Jeep Renegade. This header is nearly identical to the Dart header except for a change in the lower B pipe, and produced 11 HP & 12 ft-lbs of torque at the wheels. It made a very noticeable change in power that you can really feel!

This header is designed to bolt to the head and factory exhaust flange with no cutting, or welding needed. You may keep your factory engine cover on, or leave it off if you wish. Because there is a high flow catalytic converter, your car will still pass emissions testing and should not have any check engine lights. If you do happen to get a CEL, simply get in touch with us for a quick and easy solution.

2018-Present Jeep Compass owners! A Compass owner bought this header and told us it was a perfect installation with no modification required.

MPx Header & OEM Header Comparison
2.4 Dart OEM header/cat unit

This header is available in three different finishes:

  • Raw Steel - For those of you on a budget (We highly recommend using header wrap to reduce the heat in the engine bay with a raw steel header).
  • Chrome Coated - A nice shiny finish that helps prevent rust.
  • Ceramic Coated (interior & exterior) - top of the line coating that helps prevent rust, but also prevents heat from escaping the headers and into the engine bay. The ceramic coating does a fantastic job of keeping the temperature under the hood under control, and looks good with its matte silver finish.

This header comes complete with the following pieces:

  • Upper header that is 4 into 1 design, with o2 sensor bung, that bolts to the cylinder head.
  • Lower downpipe with catalytic converter with o2 sensor bung for downstream o2 sensor.
  • Exhaust manifold gasket (if you ever need a replacement you can get a OEM one from your local dealer).
  • Exhaust o2 sensor wiring extension
  • Bolts to secure the downpipe to your exhaust

    Update November 2018 : We have gotten some feedback from our tester with the Renegade MPx prototype header:

    "Hey Cory, Just picked it up an hour ago and I told my boyfriend I'm in love all over again! The sound is perfect, not to loud but loud enough to hear. I love it, and the power is amazing I'm so so thrilled with it. Thank you so much! Again thank you this is so awesome!"

    Update 1/2/2019 : More feedback from our tester:


    The header is working great. More power for off roading and I'm climbing the hill home a lot better. Performance is awesome.

    Second update 2/26/2019: Our tester continues to put on more test miles and is still very thrilled with the header. We have done another revision on the to ensure fitment is absolutely perfect.. We are continuing to test to make sure everything is perfect before releasing this.

    April 2019- We have begun shipping these units!

    September 2022- a customer installed this header onto his 2018 Compass with 2.4 engine and he told us it was all a perfect fit with no modification needed.

      Has there been MPG improvements?
      1 Answer
      • Customer Service Rep
        Because this header adds power across the entire power band, and there is no loss of power or torque, this should actually improve gas mileage. That is, IF you continue to drive the same as before. We've found most customers enjoy driving their car more with the extra power, and therefore gas mileage may drop 1-2 mpg with more aggressive driving. If you can stay out of the throttle, you'll have an improvement though!

      I also want to get the mega flow exhaust will this pair up? if they do is it just an easy bolt on or will I have to modify it?
      Thanks

        This header has the same location and style of outlet as the factory exhaust. So any aftermarket exhaust that is designed as a bolt on exhaust with your factory headers, will work fine with this header.

      Since this product has been released for about a year now, has it been tested with the compass? I drive a 2018 and was wondering if it will fit. You haven't posted any updates it seems.

      Is this header C.A.R.B. Legal ?
      1 Answer
      • Customer Service Rep
        (CARB only applies to California residents) No, definitely not. The only parts that we see that are CARB legal are usually air intake systems made by AEM, Injen, or K&N. Almost every other aftermarket performance part is NOT CARB legal for use in California.
