OEM Downpipe to aftermarket 3" catback.
Part #: 077046
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 adaptor. Use an adaptor that allows you to retain your stock donut gasket for the best solution to finally end that pesky leak.
Features:
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!

I am currently running the stock downpipe, and I just purchased a tomei exhaust (thru IIR of course). I was told to get the grimmspeed adapter just to be safe so I don’t have any leaks between the two. The fitment is perfect, the quality is great, and it includes everything needed. I would recommend this to anyone who is running the same setup.
Perfect if you don’t want to change your downpipe and want some extra sound from a 3 In exhaust
Very high quality. Can't go wrong with this adapter. Was a perfect fit. Had no issues with installation.
Good quality, fits well, but you will need to buy an OEM donut gasket to use this, I wish they made it a little more clear that you would need this.
Works as it should and great quality
