Grimmspeed's high quality, multi layered gasket is a great alternative to the other expensive gaskets on the market. Built like an OEM gasket to provide a long lasting, leak free seal, even under extreme heat and pressure.

This gasket lies between the uppipe and the turbo.
We highly recommend new lower and upper uppipe gaskets anytime you need to install a uppipe.

  • AnswerQ: Tomei EL Header/Up-Pipe Fitment EJ255/257  sjearthquakes40871256 1 year ago

    Curious as to whether this will be both a direct fit, and the proper diameter/sizing on the upper Up-pipe to Turbo connection, with a set of Tomei EL Headers. Are all the piping, collector and primary sizes the same as OEM? Reason I ask is because if Tomei happens to use different specs in these areas, than perhaps their gasket are unique to their headers application/kit, and the G.S. counterparts are simply OEM spec replacements?

    • A: Yes, this gasket will work for Tomei's up pipe.

  • AnswerQ: Double thick version of this?  cmte_souza 2 years ago

    I had this installed but unfortunately it was leaking, maybe because of bad installation. Anyway I had to disassemble it and the gasket looks good. I usually go with the double thick options from GS when available, but couldn't find one for this gasket. Does it make sense to use two gaskets? Should I use any sort of sealing product or just the gasket? Thanks

    • A: If this wasn't sealing it's likely because you have a warped flange. A lot of heat goes through this area and parts can start to disform. You may want to check the flanges on a flat surface. Also make sure the flange is free of debris that the bolts are torqued to OEM spec. Mike

    • A: UPDATE: This was not leaking at all. The leak was on the right side header collector with a shattered OEM gasket. Since it stands maybe 7 or 8 inches from the top of the uppipe and I was looking from above the engine trying to understand where the noise was coming from, I misjudged the leak spot. Checked the flanges, reused the GS gaskets and replaced the collector ones with GS, everything is great now! Thanks!
