Xforce VAREX Valved Cat-Back Exhaust

Xforce VAREX Valved Cat-Back Exhaust - GR86 / BRZ (2022+)

On-Demand Sound Control & Premium Stainless Performance

Take total command of your vehicle's acoustic personality with the Xforce VAREX Cat-Back System. Engineered specifically for the ZN8/ZD8 chassis, this system is crafted from high-quality 304 brushed stainless steel for maximum durability and corrosion resistance. The center of the system features a high-flow "hot dog" style resonator to eliminate unwanted cabin drone, while the VAREX rear mufflers provide the ultimate flexibility in sound management. Whether you’re heading out for a quiet early-morning commute or hitting the track for a wide-open session, this valved system ensures you never have to compromise between performance and comfort.

Available Variants:

- 2.5" Diameter System (SBRZ1VKCS): The ideal choice for naturally aspirated (NA) builds, providing optimal backpressure for mid-range torque and a crisp, high-pitch exhaust note.

- 3.0" Diameter System (SBRZ2VKCS): Specifically recommended for forced induction (Turbo or Supercharged) vehicles, offering the high-volume airflow required for high-boost applications.

What’s Included in the Box:

- 3-Piece Stainless Steel System: Includes mid-pipe and dual rear muffler sections.

- VAREX Control Module: Plug-and-play wiring harness with 12V accessory power adapter.

- (2) Remote Key Fobs: For instant valve adjustment from the driver's seat.

- Interchangeable 4.5" Tips: Includes both Polished Stainless and Burnt Blue tips in the box.

- Installation Hardware: All necessary gaskets, clamps, and bolts for a secure fit.

The Xforce Advantage

- Patented VAREX Valve Technology: An internal butterfly valve allows you to adjust the exhaust path from "Street Mode" (quiet) to "Race Mode" (open) and anywhere in between.

- Brushed 304 Stainless Steel: Built to withstand the elements, this system features 16-gauge mandrel-bent tubing and precision TIG welds for a long-lasting, show-quality finish.

- Customizable Aesthetics: No need to choose a tip style at checkout—every kit includes both classic polished and aggressive burnt-blue 4.5" tips to match your build's look.

- Center Hot Dog Resonator: Specifically tuned to filter out the high-frequency "rasp" common in the FA24 engine, leaving you with a deep, smooth boxer rumble.

- Simple "No-Solder" Installation: The VAREX electronics use a simple 12V plug for the cabin and water-resistant plugs for the muffler motors, requiring zero permanent wiring modifications.
