PLM Power Driven 2008-2014 WRX / 2008-2020 STI Catted Downpipe

The PLM Power Driven divorced downpipe is a straightforward way to open up the exhaust side of an EJ-powered Subaru. The full 3-inch mandrel-bent layout reduces the restriction after the turbo, helping it respond sooner and carry airflow more efficiently than the factory pipe.

This version uses a 200-cell high-flow metallic catalytic converter, one-piece stainless-steel construction, thick CNC-machined flanges, and TIG-welded joints. It also includes an additional O2 bung for a wideband sensor, plus the required gaskets and installation hardware.
