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 HEADERS EQUAL LENGTH 6 months ago
    5out of 5stars

    Fit like a old glove. Took much longer to remove OEM set up. OEM Header , up pipe and down removed. Mated right up to Grimmspeed up pipe and limited down pipe with CAT. Took 8 hrs. Just gotta put on intercooler . Higher jack stands would of been better . Grimmspeed turbo heat shield also great fits.

    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!

    QUESTIONS & ANSWERS

    • Q: Is this available in a ceramic coated model?  monkeyman4 months ago

      I cannot find one here so I suspect not, but is this part available with heat blocking ceramic coating (preferably in White as it helps blocks heat from escaping)?
      • 0 of 0 people found the following answer helpful

        A:  No, we don't ceramic coat our Headers. We do recommend it if you are planning on wrapping the Header, because just the wrap will void our warranty.

        A:  No tune is required, but to get more out of the Headers a tune is recommended. Yes, replace the gaskets with installation and only use OEM gaskets.
