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

Part #: PLM - SUB - DP30 - MP25. The Private Label MFG Exhaust Adapter Flange is a top - notch solution for Subarus with 3 - inch downpipes and 2.5 - inch OEM midpipes. It's expertly designed to stop those pesky exhaust leaks that other designs often have. The adapter features a flared 3.0 - inch flange that fits smoothly into the downpipe and then transitions to a 2.5 - inch pipe for your OEM or 2.5 - inch midpipe. It might also work for other applications. Key features include: it's brand new in the box, made of mild steel, comes with a one - year limited warranty, is a simple bolt - on solution with nuts and bolts included, has a CNC - machined flange that's about 3/8 - inch thick, a one - piece design, and 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. Take the adapter out of the box. Insert the flared 3.0 - inch flange into the downpipe. Then, slide the 2.5 - inch part of the adapter into your midpipe. Use the included nuts and bolts to secure it in place. As for maintenance, since it's made of mild steel, keep an eye out for any signs of rust. If you notice some, you can use a rust - resistant paint to touch it up. Make sure the bolts stay tight over time. Check them periodically, especially after long drives or rough roads. This adapter might work on other applications, but always double - check to ensure a proper fit.
