GrimmSpeed OEM Downpipe to 3in Cat Back Adapter
Subaru Turbo Models
Features & Product Details
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.

Not much to say other than it's an adapter and works as intended. Grimmspeed always uses quality hardware - glad to see Grade 8 bolts in the packaging.

I used this while installing a Tomei Expreme Ti on a 2019 WRX STI. It functioned perfectly. I highly recommend!

This was very easy to install for someone who has never done an installation like this before. I installed it on my 2018 WRX when I was swapping the stock exhaust for an Indivia Gemini. No leaks, and everything fit together perfectly.

Installed an Invidia N1 on my 2011 WRX, and had a leak from the downpipe to the midpipe. This plus a donut gasket and about 15 minutes of time fixed the leak extremely well. Definitely recommend if you want to install a 3” catback on a stock downpipe

A must have for anyone running a catback with the OEM downpipe! Hardware is top notch as well!

A: If you have an OEM or OEM diameter downpipe this will fit perfectly. You don't need a new donut gasket, but it is highly recommended.
