OEM Downpipe to 3in Cat Back Adapter by GrimmSpeed
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.

Bought the invidia r400 catback exhaust system for my 2021 STI. i also read comments about you needed to buy an adapter to make it fit with your stock downpipe. the grimmspeed adapter makes the perfect fit for my catback. good quality ! if your planning on buying a catback system make sure you add the adapter to your cart.
Ordered the the R400 exhaust for my wrx and luckily read the comments about this and bought this adapter at the same time as the exhaust. Exactly what was needed and bolted right up.
