Features & Product Details

What's one of the most overlooked anti-flowing Subaru pieces you ask? The stock exhaust manifold crossover. 50% of your exhaust gases are passing through this tiny pipe and which isn't good. Well here comes the solution for this problem.

Welcome the GrimmSpeed Version 2 Subaru Exhaust Manifold HiFlow Crossover. They've decided to step it up a notch with the first revision of the crossover. Meet HiFlow Crossover v2. Immaculate welds, smooth as butter 2" stainless steel, thick 12mm stainless flanges. You can't beat this piece.

Customers have seen up to 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 in the center to allow for easier installation and for thermal expansion during hard driving.

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

New hardware, as well as new gaskets, will be included to make the HiFlow Crosspipe ready for the installation.

Not happy..quality is still lacking 5 months ago
skullsyst
So, I bought this and the uppipe and both ceramic coated...quality is a bit better but quality control is lacking. Can't comment on performance on ease of install, as they are still waiting for install in a few days. Pics will speak for themselves . Outside quality is fantastic though. Too bad they cant clean up the inside though. Might want to purchase a flex hone to get this product where it should be...I get it if I were purchasing ebay stuff....but this is GrimmSpeed......i expected better. Per description... "Meet HiFlow Crossover v2. Immaculate welds, smooth as butter 2" stainless steel, thick 12mm stainless flanges. You can't beat this piece." ....don't really see smooth as butter

The part so nice, I installed it twice! 2 years ago

Replacing the crosspipe is an oft-overlooked thing. It is possibly the easiest exhaust part to modify, as all you need to remove is the collector on one side. Loosen the other, then unbolt it from either collector, and voila! Not only is it pretty and useful, but GrimmSpeed was awesome enough to include all the additional hardware to install this thing - no buying additional gaskets, these ones fit perfectly. Upon opening the box, you can see the attention to detail that GrimmSpeed give these. The coating looks beautiful and everything is well machined and constructed. I have one of these for my 07 Forester XT, and also one for my 03 WRX, because it was so simple and so awesome. One thing to be mindful of - if you are like me and do the up-pipe at the same time as this, make sure you segregate the gaskets. They are a slightly different size, and you will feel stupid if you put it back with the wrong ones in the wrong places....ask me how I know.

    Does this part replace a stock header component or is this used on an aftermarket header?
