Installed this when I was replacing my stock DP with invidia catted Dp on my 2013 wrx. Gasket is a beautiful piece of machinery and fit like a glove. You won't be disappointed with this purchase.

GrimmSpeed Turbo to Downpipe Gasket

This gasket was suggested by the RSD staff after inquiring about which gasket I would need for my Invidia DP after installing it. The gasket is of course the easiest part of the installation after adding your down pipe, but the gasket was well made and 20k miles later I have had no problems with it.

Perfect Product!

  • AnswerQ: Fitment  alemadrid11 11 months ago

    Does this gasket fit a Tomioka Racing TD05-18G Turbocharger to an invidia v2 downpipe(bellmouth)?

    • A: This gasket will fit stock replacement turbos and if the turbo is compatible with the stock gasket, then it will work with this gasket.

    • A: The bolt spacing on this gasket is the same as the OEM pattern. Both items you are fitting together should follow the same spacing, so this would be the correct gasket. -Andy

  • AnswerQ: Is this gasket re-usable?  iancrum16441 3 years ago

    Can this be re-used if it wasnt installed too long ago? or are these one use only?

    • A: You will need to inspect the gasket after removal but it should be good for quite some time! Mike
