XForce Varex Valved Rear Muffler Kit 2022-2026 WRX

XForce Varex Valved Rear Muffler Kit 2022-2026 WRX | Variable Sound Control | Performance Exhaust Upgrade

Overview

The XForce Varex Valved Rear Muffler Kit is a precision-engineered upgrade designed specifically for the 2022-2026 Subaru WRX. This kit enhances your existing XForce cat-back exhaust system by introducing the all-new Varex WR muffler design, which delivers an unprecedented range of sound levels—from near-silent OEM quiet to a deep, aggressive exhaust note. Ideal for WRX enthusiasts who want full control over their exhaust tone without sacrificing daily drivability.

Built with 304-grade stainless steel and mandrel-bent pipework, the Varex WR mufflers are engineered to withstand the thermal and mechanical stresses of spirited driving and boost pressure. The remote-operated valved system allows seamless switching between quiet and loud modes, and when paired with the optional SmartBox controller, sound modulation can be automated based on speed, throttle position, RPM, or GPS location. This thoughtful engineering approach ensures a versatile exhaust experience tailored to the modern WRX’s multi-catalytic converter setup, which tends to mute factory exhaust sound.

For Subaru WRX owners, this valved rear muffler kit unlocks the full acoustic potential of the platform, providing a customizable sound profile that enhances the driving experience without drone or harshness. The bolt-on design integrates with existing XForce mid and front sections using factory mounting points, ensuring a clean installation and reliable fitment. Whether on the street or the track, this upgrade balances performance and refinement for the discerning Subaru enthusiast.
