PLM Private Label Mfg. Power Driven 3" Resonated Midpipe Kit for Subaru WRX STI 3" 2015-2021 was made for maximizing HP gains, more flow, more Power, more Torque & more Sound without sacrificing ride height.
CNC mandrel bending 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 resonator, includes stainless steel flanges, and area direct fit to our muffler deletes / axlebacks ( not included) to be finished off with a straight-through, low-restriction racing muffler for uninterrupted flow.
