What's one of the most overlooked anti-flowing OEM Subaru pieces you ask?? The stock exhaust manifold crossover. 50% of your exhaust gases are passing through this tiny pipe. GrimmSpeed's Version 2 Subaru Exhaust Manifold HiFlow Crossover is the solution to this problem. They've decided to step it up a notch with the first revision of their crossover. Immaculate welds, smooth as butter 2" stainless steel, and thick 12mm stainless flanges. You can't beat this piece. 


Customers have seen up to a 15 HP increase when combined with a PnP Subaru Exhaust Manifold. This unit is built from 1.92" 304 Stainless Steel throughout, maximizing exhaust flow from cylinders 1 and 4 to the manifold collector for faster turbo response. This unit has a flex point in the center to allow for easier installation and for thermal expansion during hard driving. 

Add on GrimmSpeed's Ceramic Heat Coating to help keep the heat in and speed up those exhaust gases even more.

This includes all the gaskets necessary for installation.

RalliTEK branded products are warranted to the original owner against manufacturing defects in materials and workmanship for the lifetime of the product.

If a RalliTEK branded product covered by this warranty fails due to a manufacturing defect we will repair the product, without charge, or replace it at our discretion. This policy covers only original, unaltered, and unmodified materials and workmanship. This warranty does not cover damage caused by incorrect installation, accident, improper care, negligence, normal wear and tear, or the natural breakdown of colors and materials over extended time and use. Damage not covered under warranty may be repaired for a reasonable rate and a fee will be charged for return shipping.

For warranty evaluation, please contact RalliTEK Customer Service at (503) 619.0055 or info@rallitek.com to obtain a return authorization. Once this step has been completed, your product must be returned directly to the RalliTEK Warranty Department, 13339 NE Airport Way, Suite 500, Portland, OR 97230.

  • This warranty gives you specific legal rights; you may have other rights, which vary from state to state.
  • This warranty does not cover products sold by RalliTEK that are not RalliTEK branded products.

The RalliTEK website sells discontinued, special markup, and slightly blemished products at significant discounts as 'factory seconds' products. This warranty does not automatically cover products purchased as factory seconds. RalliTEK reserves the right to determine if any warranty applies on a case-by-case basis for factory second parts. If approved, the RalliTEK Warranty Department may repair factory second products for a reasonable charge and applicable shipping charges.

MANUFACTURER WARRANTIES (FOR NON-RALLITEK BRANDED PRODUCTS)

Non-RalliTEK branded products do not have any written or implied warranties. Products on RalliTEK.com are sold with the warranty applied directly from the manufacturer. The customer must contact the product brand manufacturer for any warranty details. All products sold by RalliTEK are intended for off-road and/or race use only, as suggested by the manufacturer, and should be installed and set up by professional service centers only. RalliTEK is not responsible for any product failure or failure due to installation. Should a warranty claim arise, the customer and the manufacturer will handle all warranty issues directly.

There is no warranty on high-performance or race-related parts due to the nature of usage.

No payment or reimbursement shall be made for installation, removal, transportation, or other charges. The remedies outlined in this instrument are exclusive and the liability of RalliTEK with respect to any sale shall not exceed the price of the product on which the liability is based.

EXCEPT AS STATED OTHERWISE IN THIS WARRANTY, RalliTEK MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. RalliTEK shall not, in any case, be liable for special, incidental, consequential, indirect, or other similar damages arising from any breach of these warranties even if RalliTEK or its agent has been advised of the possibility of such damages. Some states do not allow the exclusion or limitation of incidental or consequential damages so the above limitation or exclusion may not apply to you. This warranty is governed by the laws of the State of Oregon.
