The fit was excellent and install went very smoothly. Maybe a bit quicker spool but hard to tell. RSD as always was excellent!

GrimmSpeed is Awesome!

I had this product on my 2004 Forester STI conversion for quite a while when the flex joint started to leak. GrimmSpeed stepped up in a big way, when they didn't have to and replaced my pipe with a new one and only asked that I return the old one so they could see why the flex joint failed to make their products even better. This was certainly a step above an beyond. As for the product itself, great quality, perfect fitment as with all of their products! I am always happy to leave comments for products that I highly recommend, and GrimmSpeed doesn't disappoint in this regard! You want a product that will perform and hold up as advertised, this one does!

Great piece.

Received the part very quickly from RSD. The part itself seems well built and the coating is a nice touch. I bought this to replace an older grimmspeed crosspipe I had installed on my car due to the flex joint leaking. Gaskets are top notch and the hardware is the correct size. I already have PnP OEM headers so all I needed was a retune to compensate for the lack an exhaust leak. Install was easy. Definitely a must have part paired with this combo.

Balanced power gains and better tone
NIC08899 1 year ago
I'm rolling a 2012 WRX hatch. Had the Cobb SF intake, Perrin TMIC, Cobb Crank Pulley, Cobb down pipe and SPT cat back with a Stage 2 flash.. I added the Perrin turbo inlet, Grimspeed Crosspipe, and Grimspeed up-pipe simultaneously. The car was fast before, but the last upgrade smoothed out everypart of the driving experience. The car is my faster off the line, spools up much quicker. I believe I made solid power gains, but don't have any dyno data to prove it. The bottom line is I've now got great airflow from the intake all the way through the motor, the thing is just balanced. Since I had to drop the right exhaust manifold and downpipe to install the up-pipe during the installation of the Crosspipe, I replaced all of my exhaust gaskets at the same time. (Exhaust manifold, cross pipe, up-pipe, and down pipe) That might have been over kill, but now I know everything is in tip top shape and the tone coming out of my car since these upgrades is just solid. Port and polish to follow in the future. As mentioned above, I noticed power gains, but don't have any data to prove it. I'm guessing I'm putting 300-325 to the wheels, my access port said I was putting out 354 but that is probably a bit high. Bottom line: if you're NOT going with a header, get the Crosspipe..

  • Q: Invidia Uppipe  tempemail55b2949bcaae5288048b48ee 8 months ago

    Answer

    Will this bolt on properly with the Invida Uppipe? (Part #: INV HS02SW1UPP)


    • A: This bolts up to the factory header and does not attach to the uppipe. Fitment should not be effected with the Invidia uppipe.

  • Q: Header differences.  StarryBoar 8 months ago

    Answer

    So I would like to install the Tomei Experme Un-equal headers. Would this part be relevant? Or compatible? Thank you.


    • A: This is designed to be installed to the stock header and would not be compatible with aftermarket headers. As majority of aftermarket headers will be a full assembly, and the stock is a 2 piece with the cross pipe between.
