VAREX Adjustable Exhaust Technology

Unlike a conventional sports exhaust that has a fixed sound level, the XForce VAREX system incorporates an electronically operated valve inside the rear muffler.

The valve can alter the route taken by the exhaust gases through the silencer.

With the valve in the quieter setting, exhaust gases are routed through more of the muffler to reduce sound levels.

Opening the valve provides a freer-flowing route through the exhaust, producing a significantly more aggressive performance exhaust note.

This makes the ESBRZ2VKCS an excellent option for owners who want the sound of a performance exhaust without having to live with maximum exhaust volume all of the time.

3-Inch Performance Exhaust System

The ESBRZ2VKCS uses a large 3-inch exhaust pipe diameter, providing increased exhaust-flow capacity compared with the standard system.

The larger bore makes this version particularly suitable for cars running or planning substantial performance upgrades, including:

• ECU tuning
• Performance manifolds / headers
• Sports catalytic converters
• Supercharger conversions
• Turbocharger conversions
• High-output naturally aspirated builds

For turbocharged and supercharged GT86/GR86/BRZ applications, XForce specifically recommends the 3-inch version.

304 Stainless Steel Construction

The complete system is manufactured from quality 304 stainless steel, providing excellent durability and corrosion resistance while giving the exhaust a premium appearance.

The system is designed as a performance-focused replacement for the restrictive factory rear exhaust system while maintaining a high-quality fit and finish.

Centre Resonator

XForce incorporates a centre hot-dog style resonator into the system to help control unwanted exhaust frequencies and rasp while maintaining the deeper, sportier exhaust tone expected from a large-bore performance exhaust.

This helps provide a more refined exhaust note than a completely unresonated system.

Large 4.5-Inch Exhaust Tips

At the rear, the system features substantial 4.5-inch exhaust tips that fill the GT86, GR86 and BRZ rear bumper openings and provide a much more purposeful appearance.

The system includes both:

Polished stainless steel tips

and

Blue burnt-finish optional tips

allowing the owner to choose the appearance that best suits the vehicle.
