XForce VAREX 3″ Valved Cat-Back Exhaust System – Toyota GR Yaris 1.6 Turbo AWD 2020-2024 – ESTY21VKCS

XForce VAREX Performance Exhaust for Toyota GR Yaris

Give your Toyota GR Yaris the soundtrack and appearance it deserves with the XForce ESTY21VKCS VAREX Valved Cat-Back Exhaust System.

Developed specifically for the GR Yaris platform, this system replaces the factory exhaust from the catalytic-converter section rearwards with a larger-flowing 3-inch stainless-steel cat-back system.

XForce has developed the system to combine performance-oriented exhaust flow with everyday usability. At the heart of the system is the electronically controlled VAREX rear muffler, allowing the driver to alter exhaust volume and character depending on the situation.

VAREX Valved Exhaust Technology

Unlike a conventional fixed-volume performance exhaust, the XForce VAREX system incorporates an electronically controlled valve inside the rear muffler.

This allows you to switch between a quieter setting for everyday driving and a more aggressive exhaust setting when you want to hear the GR Yaris’s turbocharged three-cylinder engine.

An optional XForce SmartBox can also provide smartphone-based control and additional customisation.

3-Inch Performance Exhaust

The ESTY21VKCS uses a 3-inch diameter exhaust system, helping reduce restriction compared with a more conventional road-car exhaust layout.

The system is manufactured from 304 stainless steel, providing excellent corrosion resistance and durability for cars used throughout the year in UK conditions.

Twin Centre Resonators

XForce incorporates two centre hot-dog-style resonators with an anti-resonance chamber into the system.

This configuration is designed to control unwanted resonance while maintaining the distinctive performance exhaust character expected from a modified GR Yaris.

VAREX Rear Muffler

The rear section incorporates an XForce VAREX muffler feeding twin 2.5-inch outlets.

The electronically controlled valve gives the driver substantially more control over the vehicle’s exhaust character than a conventional permanently loud cat-back system.

Polished 4-Inch Exhaust Tips

The system is finished with large polished 4-inch angle-cut exhaust tips, giving the rear of the GR Yaris a more aggressive appearance while complementing the factory performance styling.
