GrimmSpeed 3" Downpipe to OEM Cat-Back Adapter

Exhaust leaks seem to be an all-too-common issue with most modded Subaru’s. 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.

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 they flared out one end to just shy of 3" so that unlike other adapters, this one will not block flow!
