PLM Private Label Mfg. Power Driven 3" Non-Resonated Midpipe Kit for Subaru WRX STI 3" 2015-2021 was made for maximizing HP gains, more flow, more power, more torque & more sound!

Precision CNC mandrel bend tubing allows for a constant tubing diameter throughout the bend, which results in precise fitment as well as improved exhaust gas flow.  Each system is fitted with a straight pipe to eliminate the resonator, includes stainless steel flanges, and area direct fit to our muffler deletes / axle-backs (sold separately) to be finished off with a straight-through, low-restriction racing muffler for uninterrupted flow.
