PLM Axle-Back Exhaust – Subaru WRX & STi Sedans 2011–2014
SKU: PLM-SUB-TKP-DUAL-2011-PO

Upgrade your 2011–2014 Subaru WRX or STi sedan with the PLM Private Label Mfg. Axle-Back Exhaust, designed for enthusiasts who demand performance, sound, and style. Often called muffler deletes, track pipes, or muffler bypass, this high-performance axle-back exhaust removes the restrictive factory mufflers to deliver a more aggressive tone, enhanced throttle response, and reduced overall weight.

Constructed from 16-gauge TIG-welded stainless steel, this lightweight system ensures long-lasting durability and corrosion resistance. Precision mandrel-bent piping and CNC-machined flanges guarantee perfect fitment and optimized exhaust flow. The staggered 3.5-inch single-wall tips are available in either polished stainless steel or blue-titanium burnt finish, giving your WRX or STi a sporty, standout appearance.

Installation is quick and hassle-free, with direct bolt-on compatibility to the OEM mid-pipe. OE-style exhaust hanger rods make alignment simple, while the system’s lightweight design reduces overall rear-end weight compared to the factory mufflers, improving both performance and handling. This exhaust pairs perfectly with other PLM performance components to complete a high-flow, low-restriction exhaust system.

Whether you’re on the street, at the track, or enjoying spirited canyon drives, the PLM WRX/STi axle-back exhaust delivers deep, aggressive sound, improved performance, and a clean, aggressive look that elevates your car’s presence.
