The3" Downpipe Adapter - Aftermarket DP>OEM Catback - 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!
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.

Compare our adapter to the competition and you will immediately see why we offer the best solution to finally end that pesky leak.
