"Good Quality"
A perfect solution to pesky problems - it's what you expect from GrimmSpeed!
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. The most guaranteed leak you will get though is if you run an aftermarket 3" downpipe to an OEM or OEM like 2.5" Exhaust. Compare our adapter to the competition and you will immediately see why we offer the best solution to finally end that pesky leak.
Cut from Steel and hand welded these pieces were born tough. With the ability to work with both flat style gaskets AND donut gaskets they cannot be matched. If that wasn't enough we flared out one end to just shy of 3" so that unlike the competitors, our adapter will not block flow!
QUICK SPECS:
- Flared adapter transition creates a smooth transition from your 3" downpipe to your OEM midpipe
- Flanged for OEM Donut Gasket
- Indestructible Steel CNC Laser cut construction
- Simple bolt on installation with included hardware
- Will Not obstruct exhaust flow like other adapters - Flared end guarantees smooth exhaust flow
NOTES:
- GrimmSpeed 3in. Gasket and OEM Subaru Donut Gasket SOLD SEPARATELY
- Adapter is only intended to be used for connecting aftermarket 3in Downpipe to OEM style catback. It can not be used in reverse.

"Perfect"
Adapter
"Great adapter of 3" down pipe to OEM catback. Fits perfectly"
3 to 2.5 exhaust adapter
"Great product, used it on my g37s to mount a 3inch ISR y pipe to stock 2.5 inch mid pipe, just had to cut the 2.5 side that comes off the mounting flange!! Looked everywhere no one makes something like this for the Z or Gs very happy I found this in a fourm"
Great product
"Just like every other product we purchase, Grimmspeed delivers excellent quality products"
Quiet sleepy Foresters..
"Got this & the downpipe gasket to interface the Grimmspeed divorced downpipe to the factory stock catback on a 2013 Forester XT. I like the ability to have high performance with quiet exhaust that keeps the car looking stock & slow. The absolute best thing about using this is that my tuner says he can tune my car for even higher performance with the VF52 upgrade - unimpeded by the factory quiet exhaust! Talk about a sleeper!"
3” DP to stock Catback
"Listen, I’m building a sick Forester XT sleeper and wanted to keep the stock exhaust for phase 1..... so I’m smart and do what Einstein, Copernicus and Musk would do... I turned to Art and the grimmspeed gang and made power with quality parts. This is exactly as advertised and has PERFECT Fitment."
No more leaks
"I needed to stop an exhaust leak and this adapter sealed it nicely. My J-pipe isn't from Grimmspeed, but it works just fine. I bought it with the thicker 3" gasket and donut gasket. Now I have proper boost pressure."
Great product
"Great quality part and all hardware was included. No fitment issues whatsoever. Always a pleasure doing business with you."
Excellent Choice...
"I recently purchased a 2nd one. The first one I gave to my brother along with a my stock STI exhaust to fit up to his FXT w/downpipe. It was still in great shape and installed perfectly. The new one I got was fresh and well constructed just like the first. Price is right, quality is great, service is 2nd to none, and I have another GrimmSpeed sticker to add to the collection. :D"
