PLM Subaru Up Pipe – WRX, STI, Forester XT, Legacy GT & Outback XT (1991–2021)

SKU: PLM-SUB-UP-PIPE-IWG

Product Description

The PLM Private Label Mfg. Power Driven Subaru Up-Pipe is designed to improve exhaust flow, reduce turbo lag, and increase overall performance on EJ-series turbocharged Subaru platforms. By replacing the restrictive factory up-pipe, this upgrade allows exhaust gases to flow more efficiently to the turbocharger, resulting in quicker spool and improved power delivery across the RPM range.

Constructed from high-quality 304 stainless steel, this up-pipe features 14-gauge piping, a 0.5-inch thick flange, and precision CNC mandrel-bent tubing for maximum durability and performance. The integrated high-quality flex joint is strategically placed away from sharp bends to reduce stress and significantly extend service life compared to lower-quality designs.

Designed as a direct bolt-on replacement, no modifications are required when installing this up-pipe to the OEM exhaust manifold or turbocharger. Hand TIG welded for strength and consistency, this up-pipe is an ideal upgrade for daily-driven vehicles and performance builds alike.
