Description

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.

  • Q: Headers/oil filter  FFMboy12 1 month ago

    Answer

    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?


    • A: No, the extra heat will not cause any extra damage.

  • Q: Warranty  zeus1890 2 months ago

    Answer

    A. Does adding these headers void the car warranty? B. Does wrapping the headers void the header warranty?


    • 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 pan 4 months ago

    Answer

    Do I absolutely need to replace my oil pan in order for this header to work ?


    • A: Yes, You will need to swap to an STI oil pan and pick up to run this on a WRX

  • Q: 03 wrx fitment  Nelson Asay 5 months ago

    Answer

    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?


    • 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.

  • Q: 2016 Subaru STi   Mj 6 months ago

    Answer

    Is this fit to 2016 Subaru STi. I have a 44mm Grimmspeed external wastegate uppipe with 2 bolts. This header has 2 bolts from uppipe ? Also do I need a different oil pan if I install this header on my 2016 STi.


    • A: Yes, this would work with your Grimmspeed EWG Up-Pipe and you won't need a different oil pan.
