XForce Twin 2.5" to 3" 304 Stainless Steel Cat Back Exhaust System With VAREX Audi RS3 8V 17-21 Sedan

XFORCE offers a range of uniquely engineered and designed stainless steel bolt on exhaust systems. These exhaust systems bolt directly to existing mounting points making installation easy. They are built to perform well, with materials designed for longevity and like all XFORCE exhaust systems they look great!

The unique header design increases power throughout the rev range, while providing a great engine audio note – make it roar!

VAREX Mufflers use our patented technology to combine both the design of the stock muffler and the performance muffler into one single compact unit. A sophisticated butterfly valve mechanism is implemented to redirect the exhaust gas flow and vary between the two. For higher sound level, the exhaust flows are directed through the opening path and produce maximum power with a robust sound level (or the “sports car note”) and near-zero resistance.

Whilst for lower sound level, the exhaust flows are directed through the chambered path (similar design with the stock muffler) and produces a minimum sound level that gives you the best in-car comfort. The angle of the valve is also controllable, which can be adjusted to stop at various points between sports mode and silence mode. This gives you further freedom to set the optimal sound level according to your desired preference.

• Street Mode: Setting Varex muffler in 'Street mode' enables lower sound levels and maximum discretion, as exhaust gases are directed through a chambered path as would a stock muffler
• Race Mode: For greater power output and sound leve, exhaust gases are directed through the opening path and produce maximum power with a robust sound level (or the 'sports car' note) and near-zero resistance
• In Between Mode: As the angle of the valve is infinitely adjustable, it can be adjusted to stop at any point between street mode and race mode. This gives you further freedom to set the optimal sound level according to your desired preference.
