3" 304 Stainless Steel Varex valved Cat Back Exhaust System with Smartbox

Features

Unleash the full potential of your Audi 8Y or 8V S3 Sedan with the XFORCE VAREX SmartBox-equipped cat-back exhaust system. This system doesn’t just upgrade your exhaust—it redefines how you experience sound and control behind the wheel.

Constructed from brushed 304 stainless steel, the system features 3” mandrel-bent piping, a hot dog resonator, and a redesigned VAREX valved rear muffler, giving you a bold, aggressive tone when open and a refined, near-stock sound when closed. It’s daily-driveable with the flexibility to turn heads when you want to.

Paired with our VAREX SmartBox, you gain the most advanced exhaust control available. Choose from:

  • Matrix Mode: Automatically adjust valve position based on speed, RPM, or throttle input.

  • Manual Mode: Fine-tune valve position in real time via the XFORCE app or remote.

  • Geo Mode: Program valve behavior by location—quiet in your neighborhood, loud on your favorite backroad.

  • Factory Mode (with optional cable): Seamlessly link exhaust behavior to your Audi’s built-in drive mode settings.

Finished with bold quad 4” tips (available in brushed, black, or burnt blue), this system not only transforms your S3’s sound but also delivers a premium visual upgrade.

System Features:

  • 3” mandrel-bent 304 stainless steel construction

  • Drone canister tube for reduced cabin drone

  • Redesigned VAREX valved muffler for maximum sound range
