GrimmSpeed Subaru OEM Downpipe to 3" Catback Adapter - Multiple Subaru Fitments


Exhaust leaks seem to be an all-too-common issue with most modified Subarus. They tend to spring up out of nowhere and cause hours of troubleshooting headaches. Compare our adapter to the competition and you will immediately see why we offer the best solution to finally end that pesky leak.

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. The other most common leaks that we hear about is from running an OEM downpipe with an aftermarket 3" catback without a proper adaptor.

 Stock Downpipe to Aftermarket 3 inch Catback Adapter:

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!

Features: 

  • 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!)

NOTE: GrimmSpeed 3in. Gasket and OEM Subaru Donut Gasket SOLD SEPARATELY*
