PLM 3in to 2.5in Exhaust Adapter Flange Subaru WRX / STI 2002-2021 EJ Models

Part #: PLM - SUB - DP30 - MP25. The Private Label MFG 3” to 2.5” Exhaust Adapter Flange is perfect for Subarus with 3 - inch downpipes and 2.5 - inch OEM midpipes. It's designed to prevent exhaust leaks that are common in other designs. The flared 3.0 - inch flange fits into the downpipe and smoothly changes to a 2.5 - inch pipe that goes into your OEM or 2.5 - inch midpipe. It can be used with 3 - inch downpipes and 2.5 - inch OEM midpipes and might work for other applications too. Features include being brand new in the box, made of mild steel, having a one - year limited warranty, being a simple bolt - on solution with nuts and bolts included, a CNC - machined flange that's about 3/8 - inch thick, a one - piece design, and it won't block the exhaust flow.

Using this exhaust adapter flange is easy. First, make sure your Subaru has a 3 - inch downpipe and a 2.5 - inch OEM midpipe. You can try it on other applications, but there's no guarantee it'll fit. Just insert the flared 3.0 - inch flange into the downpipe and the 2.5 - inch pipe into your midpipe. Then, use the included nuts and bolts to secure it in place. As for maintenance, since it's made of mild steel, you should keep an eye out for rust. If you notice any signs of rust, clean it off and apply a rust - resistant coating. And remember, it comes with a one - year limited warranty, so if you have any issues within that time, you can reach out for support.
