PLM Power Driven Subaru EWG 3-Bolt Up Pipe & Dump Tube – 38mm / 40mm

SKU: PLM-SUB-UP-PIPE-EWG-38MM-3B

Product Description

The PLM Power Driven Subaru External Wastegate Up Pipe with Dump Tube is designed for serious turbo Subaru builds running aftermarket 3-bolt headers. Engineered for maximum exhaust flow and boost control, this up-pipe supports both 38mm and 40mm external wastegates, giving you flexibility as your setup evolves.

Constructed from high-grade 304 stainless steel with thick-wall piping and a reinforced flex joint, this up-pipe is built to handle high heat and extreme boost conditions. Precision CNC mandrel bends and minimal internal steps help improve exhaust gas velocity, reduce turbo lag, and unlock noticeable horsepower gains.

The integrated dump tube allows excess exhaust gases to exit efficiently, ensuring stable boost control and consistent performance. This system is a direct bolt-on solution for Subaru EJ-series engines equipped with compatible 3-bolt aftermarket headers.
