Product Description

Perrin Performance PSP-EXT-055 - Perrin Performance Subaru Forester XT Equal Length Header 1.5" Primaries; 2004-2013.

Create a smooth sounding exhaust note while increasing horsepower and torque with the PERRIN E4-Series Equal Length Header. Completely Redesigned - The new PERRIN E4-Series Equal Length Header comes with collectors that have been designed for better exhaust flow while allowing the headers to be constructed much more accurately. The improved exhaust flow and more precise construction increases power and reliability. The new E4-Series also has a low-profile design, allowing for excellent of ground clearance. The equal length design of the PERRIN E4-Series Header produces smooth, balanced exhaust flow from the heads to the turbocharger giving you the best of two worlds: quicker turbo response as well as more horsepower and torque throughout the entire RPM band. While designed to fit to the factory up-pipe, our header will also mate with an aftermarket up-pipe that fits factory header and turbo, as well as any rotated turbo kits compatible with the factory header.

You won't see grossly over-sized tubing to make our header look impressive, this just slows exhaust gas flow and reduces response. PERRIN headers uses 1.5 and 1.625 (big tube) primary tubing that is expanded at the flange to fit the Subaru exhaust port size. These tubing sizes are perfectly designed for cars up to about 400 wheel horsepower and above 400 wheel horsepower, respectively. You can see from our dyno graphs that there is a significant gain in horsepower and torque across the entire RPM band compared to an OEM Subaru header.

PERRIN Flanges are CNC machined from 304 stainless steel and counterbored on the back side to make smoother transitions. Flange ports are sized properly to ensure exhaust coming out of the head has a smooth, unobstructed path to the tubes. The ports are not over-ported which would cause gaskets to burn out quickly. The tubes are expanded inside the flanges for a perfect fit and smooth flow of exhaust gases to the tubes.

Due to its equal length design, the PERRIN Header will alter the tone of your exhaust. The exhaust pulses from the engine are equalized and spread out producing a smoother, more refined sound. A byproduct of the equalization is a significant reduction in the volume of your exhaust sound. Some describe the sound as being similar to an inline four cylinder engine exhaust.

Most headers collect on the passenger side of the engine, and due to space constraints, are not equal length and compromise exhaust flow. Because we use the added room provided by the oil pan (only on 2.5L turbo pans), we can create a smooth transition of the header primaries to the collectors, and collectors to up-pipe, providing more power and torque then the competition.

PERRIN E4-Series Equal Length Headers feature a brushed stainless steel finish.

2.0L WRX engines will need the 2.5L STI oil pan install kit.

SPECIAL NOTE ABOUT SUSPENSION & EMISSIONS RELATED PRODUCTS:

Many modifications (and combinations of modifications) are not recommended and may NOT be permitted in your country, state or other form of local government. Consult your owner's manual, instructions for each product and all laws before undertaking these modifications. The owner and user are solely responsible for the legality and safety of the vehicle you modify using these components! ALTA and PERRIN Performance are not responsible for any physical or financial damages as result of proper or improper installation, usage or ownership of this product. Use of suspension products will result in a change in the handling characteristics of your vehicle. As with ANY vehicle, extreme care must be taken to prevent loss of control or roll-over during all driving maneuvers. Always wear seat belts, and drive safely, recognizing that reduced speeds and specialized driving techniques may be required. Failure to drive this vehicle safely may result in serious injury or death! Once installed do NOT drive the vehicle unless you are familiar with its unique handling characteristic and confident in your ability to maintain control under all driving conditions.

All engine and exhaust components (Including but not limited to the following: turbo systems, ECU Tuning, exhaust pipes, intake systems, supercharger pulleys, intercoolers etc.) have been designed and intended for off-road applications only. These components are legal in California for racing vehicles only, which may never be used on public roads or highways. Federal and many state laws prohibit the removal, modification or rendering inoperable of any device or element of design affecting vehicle emission or safety in a vehicle used on public highways. Violation of such laws may subject the owner or user to a fine or penalty. Check your local and federal laws prior to installation! Installation of performance products may void vehicle warranty coverage, if any, on your vehicle. Vehicles modified by the use of performance parts may no longer be lawfully used on public highways. Re-sellers, installers and end users assume all costs and risk associated with these items. ASMC LTD. is not responsible for any losses incurred from the use of any and all products sold.

SPECIAL NOTES ABOUT EXHAUST RELATED PRODUCTS.

We will not warranty any exhaust part that either fails or has warped flanges due to header wrap being installed. While header wrap protects the engine from heat as well as provides some performance benefits, it greatly reduces the life of any stainless steel part. Header wrap greatly increases the rate of corrosion, added to that the actual temperature of the metal is much hotter, reducing its lifespan even further. Operation of vehicle without installation of splash guard will void warranty.

We will not warranty any flanges that are warped away from the weld if any aftermarket gaskets are used. Only OEM Subaru / Toyota gaskets are to be used on PERRIN Exhaust parts, with the exception of downpipes for turbo kits. Subaru / Toyota provides the proper crush gasket that still becomes flat when tightened (or over tightened) in comparison to aftermarket gaskets which can have a crush ring that is too thick, causing a hot-spot in the middle of the flange. These will warp the flanges of your PERRIN exhaust, causing a permanent exhaust leak that will not be fixable with a new gasket.
