Product Description

The PLM Axle-Back Exhaust, also known as muffler deletes or track pipes, is one of the most popular upgrades for the 2015–2021 Subaru WRX and STI. Designed to replace the large, restrictive factory mufflers, this system delivers a more aggressive exhaust tone, improved flow, and significant weight reduction while maintaining an easy bolt-on installation.

Constructed from mandrel-bent stainless steel and fully hand TIG welded, the PLM system provides durability you can trust for both daily driving and spirited performance use. The dual-exit layout allows for the most direct exhaust path possible, helping the turbo breathe more efficiently while giving the car the deep, sporty sound enthusiasts want.

Each side weighs approximately 8 lbs, for a total system weight around 16 lbs, offering a noticeable reduction compared to the bulky OEM mufflers.

Available with your choice of Polished or Titanium Blue gradient tips, this is a simple upgrade that transforms both appearance and sound in minutes.
