PLM Power Driven 3" Resonated Mid Pipe Subaru WRX STi 2015–2021
SKU: PLM-SUB-MID-2015-RES

Improve exhaust flow, refine tone, and unlock additional performance with the PLM Power Driven 3-inch Resonated Mid Pipe for the 2015–2021 Subaru WRX and STi. Designed for enthusiasts who want a strong balance between power and sound control, this midpipe increases flow while using a carefully selected resonator to keep the exhaust note deep and clean without excessive rasp or drone.

Manufactured from high-quality stainless steel, this system features precision CNC mandrel bends that maintain consistent pipe diameter for smoother exhaust velocity and improved efficiency. The integrated Y-collector is built using stainless cast construction, promoting balanced flow to both rear sections of the exhaust.

The resonated design is ideal for drivers who want noticeable gains and a more aggressive character while still retaining the unique Subaru rumble. Whether paired with PLM axle-backs or muffler deletes, the result is a refined, performance-focused exhaust system suitable for both street and spirited driving.

Every unit is professionally TIG welded and finished with CNC machined flanges to ensure durability, proper sealing, and straightforward installation. This kit is engineered as a direct bolt-on solution to PLM axle-back systems, and includes the necessary gaskets and hardware to make installation simple.

If you’re looking to wake up your WRX or STi with better response, stronger mid-range pull, and a controlled but aggressive tone, the PLM resonated mid pipe is an excellent upgrade.
