Mishimoto Subaru Exhaust Adapter, Stock Downpipe to 3in Exhaust

If you're upgrading your turbo Subaru's exhaust, you'll want to make sure everything seals up tight. This Mishimoto exhaust adapter is designed to bridge the gap between your stock downpipe and a 3-inch aftermarket exhaust system, preventing those annoying exhaust leaks that can kill your tone and performance. It's a common scenario when combining different exhaust components, and this adapter makes the transition smooth and leak-free.

Built from 304 stainless steel, this adapter is well-made to resist rust, even in harsh climates, so it'll hold up over time. It's designed to mate directly with the stock flange on a 2015 WRX, and it works great with Mishimoto's own 2015+ WRX/STI Cat-Back Exhaust. Installation is straightforward, often taking less than 15 minutes, and it comes with all the necessary stainless steel hardware and a new 3-inch 2-bolt flange gasket to get the job done right.

This adapter fits a wide range of Subaru models, including the Forester, Impreza, and WRX STI, making it a versatile choice for many Subaru owners looking to fine-tune their exhaust setup.
