XForce Performance Exhaust is proud to unveil the all-new Varex WR Valved Muffler — our most advanced muffler design to date. Developed in response to the growing challenge of sound suppression in modern vehicles equipped with multiple catalytic converters, the Varex WR sets a new industry benchmark for performance sound control.
Why a New Design Was Needed
Modern performance cars are becoming quieter due to the increasing number of catalytic converters. While this helps with emissions compliance, it dulls the auditory excitement that car enthusiasts crave. Earlier Varex systems already allowed drivers to switch between high-performance sound and OEM-level quiet. But the latest generation of vehicles demanded more.
We needed to push boundaries — again.
Over 12 Months of Relentless R&D
Our engineering team spent over a year developing, refining, and torture-testing a completely new muffler design. The goal? To dramatically increase volume in the open valve position while still preserving the ultra-quiet characteristics Varex is famous for when closed.
The result is the Varex WR — a revolutionary design that delivers:
- The widest sound range on the market
- Deeper, louder exhaust tone when open
- OEM-level quiet when closed
- No compromise on comfort — zero cabin drone
This isn’t just a marginal improvement. It's a leap forward in what valved mufflers can do.
The Original Innovator — Now Even Better
XForce pioneered valved exhaust technology with multiple patents dating back over 20 years. The Varex WR builds on that legacy, evolving the system for today’s modern performance platforms. Whether you drive a turbocharged four-cylinder or a high-output V6 or V8, the Varex WR gives you full control over your exhaust note, adapting to your environment, your mood, and your driving style.
