Description
The PLM Power Driven Subaru 44mm External Wastegate (EWG) Up-Pipe with Dump Tube features a uniquely designed up-pipe that gives you the option to install either a 44mm or 45mm external wastegate. Designed for Subaru turbocharged applications, this high-flow EWG up-pipe helps improve exhaust flow, reduce turbo lag, and provide better boost control.
External wastegates can help achieve quicker turbo spool by reducing turbulence in the exhaust stream while providing more precise boost control. Depending on your engine, turbocharger, tuning, and overall setup, this PLM EWG up-pipe can deliver 10–40+ WHP gains.
The PLM Power Driven Subaru EWG Up-Pipe is designed as a direct bolt-on replacement with no modifications required. It bolts directly to the OEM exhaust manifold/header or turbocharger, making installation straightforward while providing a high-flow exhaust path for performance-focused Subaru builds.
