This is GrimmSpeed’s Double Thick Gasket, and it fits between your exhaust manifold, and uppipe. What makes this gasket special is that it has 12 layers, which is double the size of your standard GrimmSpeed uppipe gasket. Whenever removing, or replacing any of your uppipe, you should always replace the gasket. 

Save yourself time and labor by using a gasket thick enough to seal the uppipe right on the first try.

Good gasket and fitment
Elliott 6 months ago
Much thicker then stock so i was curious how it would fit, but i had no problems what so ever. Would recommend to anyone changing out an up pipe or exhaust manifold. Gotta have new seals!!

Double thick gives me warm and fuzzys. Great gaskets that help ensure a good seal. I wish they made them for everything I own!

Its a thick gasket, what do you want from me?
Dylan 3 years ago
It works. It helps seal up any leak you may (probly do) have from the header to the up pipe.

  • Q: Same as lower?  bruins37199161519 2 years ago


    Is this the same as the lower Uppipe gasket grimmspeed makes? Part 026001

    • A: The difference between the gaskets is the thickness. This is a Double Thick gasket that will seal better and last longer. Otherwise they are the same fitment.

  • Q: GRM003002  Marco 4 years ago


    Would this work with the grimmspeed ceramic uppipe part # GRM 003002? Thank you

    • A: Yes this is designed to work with our pipe. Mike

    • A: Yes, but if you are planning to purchase GRM 003002 it does come with all the gaskets required for installation.
