Description

This is the Grimmspeed OEM Downpipe to 3in Cat Back Adapter. This particular adapter is very popular for those of you who are retaining the stock downpipe and need to eliminate any exhaust leaks associated with the addition of an aftermarket 3" cat-back exhaust system. This adapter will allow you to retain your stock donut gasket to make for a great solution to eliminate the exhaust leak where the stock downpipe and your aftermarket 3: cat-back exhaust system will meet. 

Grimmspeed CNC machined this gasket from mild steel then had it zinc coated for extra durability and longevity. This gasket is also made in a double thickness sizing to provide a perfect seal.

Hardware will be supplied to make this adapter ready for the installation.

It Works
Fox 5 months ago
Nice gasket that does the job between the oem downpipe and my new ETS catback. It provides the proper sealing of exhaust gases and includes nice hardware. The oem hardware did have nice springs to allow for flex, which the Grimmspeed does not.

Make sure you need it before you buy it.

I was told and read that you need this to bolt up a cat back to your aftermarket stock style downpipe. No. You don’t. You only need this is you’re bolting a cat back up to the STOCK downpipe. So while I love grimmspeed gaskets etc I really didn’t need this.

Perfect fit

I ordered this adapter with my Tomei Expreme Ti purchase for my 2017 Subaru STI. It fits perfectly from the downpipe to the catback. I would recommend this adapter over the provided gaskets from Tomei.

Saved my install
FranklinWaters 12 months ago
The shop that installed my Invidia N1 race exhaust ended up cutting off the flange for the stock downpipe and welding this on to install the CBE. It made the install easier and would have made it easier for me if the level of rust did not cause me to take the car to a shop to do it.

  • Q: Installing Invidia Downpipe to N1 Race Exhaust  Zystus 3 months ago

    Answer

    I am currently using this on my stock DP with the Invidia N1 Race Exhaust but now I am going to buy an Invidia Downpipe, would this still work? Or do I have to buy another gasket for the set up?


    • A: This will work while you're running the OEM downpipe. Once you install the Invidia, you'll just want a regular 3" 2 bolt gasket.

  • Q: Correct adapter??  GeorgeV 8 months ago

    Answer

    I will be going with the COBB resonated j-pipe and the Invidia N1 catback. Is this the right adapter or what do I need? Can’t find a solid question. Thanks!


    • A: Yes, this will be the adapter you will need.


      Tyler A. 8 months ago
    • A: Answered my own question when I bought the Cobb downpipe and Invidia cst back: no you do not need this. Kinda peeved I wasted the money when the Cobb comes with a regular flange and just an adapter for the stock donut style.
