Xforce Varex Valved Cat Back Exhaust System - 2011-2021 WRX SEDAN , 2011-2021 STI SEDAN

Introducing the latest evolution in XFORCE performance exhaust sound, designed specifically for the Subaru WRX G3 S2 Sedan & VA. Built for enthusiasts who demand more sound, style, and control, our all-new 3” mandrel-bent VAREX valved cat-back exhaust system is engineered to bring out the best in your WRX.

We’ve integrated flex bellows at the front, designed to absorb engine movement and reduce stress on the system, ensuring durability and reliability under all driving conditions. This system features a 3” high-flow center section with a hot dog resonator, optimizing exhaust flow while refining sound quality. A cast stainless steel Y-piece with an XFORCE logo smoothly transitions from single 3” to twin 2.5” piping, delivering a balanced exhaust tone and aggressive rear-end look. At the rear, quad 4” polished tips complete the bold aesthetic, giving your WRX a commanding presence on the road. Additionally, the exhaust offers superior adjustability, making installation seamless for different fitment needs.

We listened to our customers and developed an all-new VAREX valved muffler, delivering 10% greater volume variation than our previous systems. When fully open, the new design produces a much louder, aggressive, and throaty exhaust note, amplifying the signature Subaru boxer rumble. When closed, it maintains a refined, street-friendly tone—noticeable but never intrusive, making it perfect for both spirited driving and daily commutes.

To ensure peak performance and sound quality, we extensively engineered and tested these new VAREX valved mufflers on a Subaru VA STI (EJ25) and a Subaru WRX G3 S2 (EJ25). The result? A meticulously refined exhaust system that offers maximum flow, optimal sound, and enhanced adjustability—perfect for WRX owners who want a versatile, high-performance exhaust upgrade.
