Exhaust leaks seem to be an all-too-common issue with most modded Subaru’s. They tend to spring up out of nowhere and cause hours of troubleshooting headaches. One of the most common leaks that we hear about is from running an OEM downpipe with an aftermarket 3" catback without a proper adaptor. Use an adaptor that allows you to retain your stock donut gasket for the best solution to finally end that pesky leak.

CNC machined from mild steel and zinc coated for durability and longevity, this thing will outlast your car. Don't waste your time trying to get your OEM downpipe to seal without a donut gasket. In a short amount of time, they rust and corrode and will prevent you from ever getting a good seal with a typical flat gasket. Re-use your stock donut gasket along with a GrimmSpeed 2x Thick 3" Gasket for a perfect seal on the first try!

Best stock to after-market exhaust adapter around!

If your going for a cat-back exhaust with a stock downpipe, this adapter is a must to avoid leaking at the connection...

No problems. You should tell those ordering a cat back system that this adapter is recommended. I had to call, after getting my Q300 system, to clarify that should have the adapter.

Fits Like a Charm
Sunman 1 month ago
I highly recommend this part if you are retaining OEM downpipe and to aftermarket CBE to ensure there will not be any exhaust leak. It fits like a charm. My worries were that this would push the Invidia N1's out too far (i.e., showing too much tip) on my 2016 WRX, but it was just right.

Exactly what I needed. Bought the car noticed a horrible exhaust leak. Did some research and found they just slapped the invidia catback exhaust on without using this kit and tossed the donut gasket. Bough this and went to the dealership to get the donut gasket and it all bolted right up. Didn't have to remove the hangers or anything enough play to easily make it work. Install was a breeze evwn though no instrucrions came with it. Old exhaust bolts snapped when taking them off but new ones comes with the kit. If you have a stock downpipe and an aftermarket exhaust this is a must and don't forget the donut gasket.

  • AnswerQ: exhuast work  will this fit a wrx oem exhaust? 4 months ago

    Im bolting the oem wrx 05" catback. Back onto the car and was wondering if these would work. If not could you guys lead me to a prouduct that would?


    • A: This is for connecting a stock downpipe to a Aftermarket 3inch catback exhaust. If you are connecting the stock exhaust to the OEM downpipe, then you need a donut gasket. http://www.rallysportdirect.com/shop/product/sub-44022aa123-subaru-oem-donut-gasket

  • AnswerQ: COBB Catback  Matt_G 7 months ago

    Bought a used Cobb Catback will i need this to connect to my stock downpipe?


    • A: This adapter is not necessary or recommended for the Cobb catback because the Cobb exhaust already comes with a tapered flange.

  • AnswerQ: fitment  JC47 7 months ago

    Will I need this when I get the Tomei Expreme Ti Titanium Catback to fit to my stock down pipe?
