Product Details

  • 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.
  • Will Not obstruct exhaust flow like other adapters.
    (Flared end guarantees smooth exhaust flow)
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 immediatly 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!

A Final solution to pesky problems, it's what you can expect from GrimmSpeed™

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

Fitment Note: Adapter is only intended to be used for connecting aftermarket 3in Downpipe to OEM style catback. It can not be done in reverse.
