Features & Product Details

The PERRIN Big Tube Header is perfect for those of you looking to increase both horsepower and torque numbers. However because this header features 1.625” tubing, this makes for the perfect header for those employing a rotated setup looking to make more than 500 horsepower. 

The E4 Series Big Tube Header comes with collectors that have been designed to further improve exhaust flow throughout the runners in an equal fashion. This results in improved power, but additionally the new E4 series has been designed to have a lower profile for ground clearance. 

Users will also enjoy the benefits of the equal length design with balanced flow from the heads straight to the turbocharger. This results in quicker turbo response compared to the OEM manifold and improved response throughout the entire RPM range.

Plus one of the better benefits is the weight savings. The OEM manifold is constructed from a heavy, cast material that is burley, and restrictive. The PERRIN unit because of the materials is substantially lighter, and with enough patience it can be a one-person installation. 

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.

    QUESTIONS & ANSWERS

    • Q: Perrin big tube header vs Killer B oil pan  Andrew E.6 months ago

      Will this header clear the current Killer B oil pan?
    • Q: Perrin Rotated Turbo Kit Fitment  Masterxing121 year ago

      Is this ideal for a rotated 3076r kit or should I go with standard size tubing? I'm making just about 400 wheel on stock ported headers. Is there an option for an egt bung to be added?
      • 0 of 0 people found the following answer helpful

        A:  I think that this would be ideal for your setup. Unfortunately there is no EGT bung option.

    • Q: Lag  Salem2 years ago

      How it will perform with an fp black journal bearing turbo? Should i get this one or the normal tube
      • 0 of 0 people found the following answer helpful

        A:  These will be pretty laggy with a journal bearing Black, but would make a ton of top end power. Personally, I'd go for a smaller diameter collector, but the best choice will depend on your goals, tune, compression, fuel, and several other factors in your setup. If you're not planning on revving the motor to 8k+, these probably wouldn't be the best call, but if it's high revs/high power you're going for, these would be solid.
