    GrimmSpeed HiFlow Exhaust Manifold Crosspipe Ceramic Coated ( Part Number: 001002)
    Great mod, fits 2015+ STI 5 months ago
    5out of 5stars

    Great piece to add to your car if you want to upgrade your stock headers but don't want to spend $750+ for aftermarket headers and still want to keep that UEL rumble. It's high quality, ceramic coated and works great with an uppipe upgrade. Sounds a little bit louder, deeper, more of a growl. Also want to say it absolutely 100% fits my 2017 STI, and any ej257 2015+ STI

    Nice piece 4 years ago
    5out of 5stars

    Easy to install. I chose the coated for the few bucks more. I don't have to deal with wrapping or worse. This piece pretty much finished a complete exhaust. Sounds great now Super fast shipping!

    Cross pipe 4 years ago
    5out of 5stars

    So I'll start by saying I've ran the stock mani, Tomei ELH, Tomei UEL header, and full Race header. and punched this unit and spent Aprox 7-8 hrs porting and polishing, the factory collectors and ceramic coating them and by far this hits like a 2 stroke dirt bike. (Ps I'm running the domain 1.5XTR 10cm ) by far out of all the headers this is the one to beat hits crazy hard but that's part of my protune. Engine/AVCS ramps up torque then the turbo hits. Think a 250 2 stroke (CR, RM,YZ KX) what ever your flavor and apply that to your STI provided you have ported the factory collectors. Also running a GS up-pipe with Tial 38mn gate.

    Grimmspeed cross pipe  4 years ago
    5out of 5stars

    I wanted to order the cross pipe however I have read from previous reviews that the pipe leaks where the mesh catted area on the pipe is. Did you guys fix this problem? Please let me know thanks subieguy2121

    QUESTIONS & ANSWERS

    • Q: Performance   Giovanni G1 year ago

      Does this make the exhaust any louder ?
      • 0 of 0 people found the following answer helpful

        A:  It might make it slightly louder, but you may not notice it to be honest. But this will certainly help with power and underhood temps for sure :)

    • Q: Ceramic coating  capilarybinkie5 years ago

      I was wondering if this was coated on the inside also?
    • Q: Header differences.  StarryBoar5 years ago

      So I would like to install the Tomei Experme Un-equal headers. Would this part be relevant? Or compatible? Thank you.
      • 0 of 1 people found the following answer helpful

        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.
