"Perfect fit for my 2018 wrx with a r400 exhaust"
Install your aftermarket catback the right way!
Exhaust leaks seem to be an all-too-common issue with most modded Subarus. 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 adapter. Use an adapter that allows you to retain your stock donut gasket for the best solution to finally end that pesky leak.
QUICK SPECS:
- Flanged for OEM Donut Gasket
- Machined lip centers 2-Bolt Gasket
- CNC Machined Steel Construction - Zinc coated for durability
- Simple bolt on installation - Supplied with quality hardware
- Includes GrimmSpeed 3" 2x Thick Gasket for a PERFECT seal!
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 (included) for a perfect seal on the first try!
FITMENT:
- Any Turbocharged Subaru with a factory downpipe/j-pipe and a 3" Catback Exhaust

"Looks like it made well ordered it a a just in case. Didn’t need to use it."
"Good"
Leak free
"Bought a Greddy RS catback and this piece is what I just needed to keep it leak free!! definitely a good investment since I’m not sure when I’ll be adding a j pipe."
Works as expected, easy to install
"Not much else to say other than thing does its job. If you have a stock DP and are planning on replacing the catback exhaust, just buy it from here. Fast shipping!"
Works perfectly
"Bought this to install my cobb S3 CATBACK delete on my 2017 WRX, Fitment was great and install was easy . Three weeks now and its being great so far."
Sealed up my midpipe exhaust leak
"I bought the Oem to 3” catback exhaust adapter even though I thought I had tightened up the nuts and bolts to seal the oem doughnut gasket to my 3” catback exhaust in my 2011 Legacy GT. To my surprise, after installing the flange and 2x thicker 3” gasket to the oem doughnut, I got a perfect seal. My catback lines up better and no more leaks. Exhaust flow and torque is noticeable and no more exhaust leak noises under the car during startup. I think that even if you think you dont have an exhaust leak with your oem downpipe to aftermarket exhaust, get this adapter and be 100% sure. Youll be happy you did."
quality adapter
"The adapter is a hi quality piece. I ordered this along with a new donut gasket to mate up a stock downpipe to a 3 inch catback exhaust on my 2017 Forester xt. Perfect seal. Why bother attempting to use just a standard gasket to seal the most prone area for exhaust leaks. Do your self a favor and buy this. No regrets from me."
Amazing!
"Gets the job done, super easy too install and no leaks what so ever. However, after installing the catback, drive around 100 miles and tighten the bolts one more time to ensure a good, snug hold. Once again, excellent product!"
