Features & Product Details

The PERRIN E4 Equal Length Headers is one of the latest and greatest creations that feature newly designed collectors to allow for smoother flow which means even more improved performance and structural rigidity. Because of the revision on the collectors, this header produces a balanced exhaust flow from the heads which means improved spool, and more horsepower and torque throughout the entire powerband. Additionally, you will enjoy the benefits of the weight savings compared to the OEM manifold, and it can work with most aftermarket up-pipe as well as the factory up-pipe.

This header has been built with 1.5” primary tubing that is expanded to the port matched flanges, and is perfect for those of you making up to 400WHP.

Please note that the 2.0L EJ20 engines will need the 2.5L STI oil pan install kit. 

Fitment Notes:

  • 2005-2007 WRX requires 2002-2004 WRX oil cooler assembly and oil feed pipe.
  • 2002-2005 WRX requiress STi 2.5L oil pan and oil pickup tube as well as custom modification to the radiator line to the transmission.
  • 2002-2005 WRX with Automatic transmission requires modifications to radiator.
  • 2004-2008 Forester XT requires STi 2.5L oil pan, oil pickup tube, 2002-2004 WRX oil cooler assembly and oil feed pipe.

    Perrin Equal length headers sound and perform amazing. Would advise getting the Perrrin up pipe to assure correct fitment. I used all Grimm speed gaskets for this install and I couldn't be happier with the results. Sounds great and performs even better!

    We are running these headers on our 15 STI. Fitment is spot on, they sound amazing and the performance is just incredible.

    QUESTIONS & ANSWERS

    • Q: Is this mod worth it if you don't upgrade your turbo?  wraith4 months ago

      Currently I have catless turbo-back exhaust, intake, and a custom tune with an Accessport. Is the EL header worth it if I don't get a bigger turbo?
      • 0 of 0 people found the following answer helpful

        A:  Yes it is! The PERRIN ELH has a huge improvement in power and performance with the OEM turbo.

    • Q: Headers/oil filter  FFMboy125 months ago

      In pictures you can see the Perrin equal length headers run extremely close to the oil filter on the STI. Should I be concerned about damage to the filter or other components due to the heat that the headers generate?
    • Q: Warranty  zeus18906 months ago

      A. Does adding these headers void the car warranty? B. Does wrapping the headers void the header warranty?
      • 0 of 0 people found the following answer helpful

        A:  According to Perrin, wrapping the headers does void the header warranty. However, if you have the headers ceramic coated and then wrapped, the warranty remains intact. As far as the vehicle warranty, these would very likely void it, but you would want to reach out to Subaru of America for the best information regarding that.

    • Q: 2003 WRX oil pan  2003 WRX oil pan9 months ago

      Do I absolutely need to replace my oil pan in order for this header to work ?
    • Q: 03 wrx fitment  Nelson Asay9 months ago

      So i have maybe two questions. Besides the 2.5 sti oil pan and oil pickup what else would I need to make this a full bolt on fitment? Also I would like to run a Killer B oil pickup. Would this work with it or no?
      • 0 of 0 people found the following answer helpful

        A:  For the Killer B part, I am not sure on the compatibility with this guy and that STi pan. For the install itself you would still need the STi dipstick for the oil and then custom modification to the radiator line to the transmission.
