XFORCE VAREX 3″ Cat-Back Exhaust System – Audi S3 8V & 8Y

Transform the sound and appearance of your Audi S3 with the XFORCE VAREX 3″ Cat-Back Exhaust System.

Designed for the Audi S3 8V Hatchback and Sedan and 8Y Hatchback, this performance exhaust system combines 3-inch mandrel-bent 304 stainless-steel pipework with XFORCE VAREX valve technology.

The VAREX valved rear muffler gives you greater control over the exhaust character, allowing you to switch between a quieter, more refined sound and a louder, sportier exhaust note.

3″ 304 Stainless Steel Construction

The system uses 3-inch mandrel-bent 304 stainless-steel tubing, providing a durable and premium-quality construction for performance-focused Audi S3 builds.

The 3″ pipework provides a free-flowing route through the cat-back section while retaining a direct bolt-on installation design.

VAREX Valved Exhaust Technology

The XFORCE VAREX rear muffler incorporates an electronically controlled valve and remote fob, allowing the driver to control the exhaust sound.

Keep the exhaust note more refined during everyday driving or open the valve for a more aggressive and sporty exhaust character.

Drone Canister

A dedicated drone canister is incorporated into the system to help reduce unwanted exhaust resonance and improve cabin comfort during normal driving.

Quad 4″ Exhaust Tips

The system is finished with quad 4-inch double-wall exhaust tips, giving the rear of the Audi S3 a distinctive motorsport-inspired appearance.

Direct Bolt-On Installation

The XFORCE system is designed as a direct bolt-on cat-back exhaust, with installation hardware supplied.

Professional installation is recommended to ensure correct exhaust alignment, clearance and operation of the VAREX valve.
