Performance and Power of the Audi A5 Sportback TFSI S Line Quattro

The Audi A5 Sportback TFSI S Line Quattro blends turbocharged performance with refined styling, making it a strong all rounder in the 2025 lineup. Powered by a 2.0 litre turbocharged four cylinder engine paired with a mild hybrid system, it delivers between 261 and 268 horsepower and up to 295 lb ft of torque. With a 7 speed S tronic dual clutch automatic transmission and Audi’s renowned quattro all wheel drive system, the A5 offers smooth power delivery and confident traction in all conditions.

As part of this upgrade, the Audi A5 Exhaust System was enhanced with a precision resonator delete. This modification improves exhaust flow, reduces restriction, and allows the engine to breathe more freely, resulting in a sharper and more aggressive exhaust note while maintaining everyday comfort.

Advanced safety and driver assistance systems provide added confidence on every journey.

The Audi A5 Exhaust upgrade transforms the driving experience by delivering a deeper and more pronounced tone under acceleration, while remaining refined during cruising. This balance makes it ideal for drivers looking to enhance both sound and usability.

Equipped with a 2.0 litre turbocharged TFSI engine producing up to 268 PS and 400 Nm of torque, the A5 Sportback accelerates to 60 mph in approximately 5.5 seconds. It measures around 4740 mm in length, 1840 mm in width, and 1380 mm in height, with a curb weight of about 1715 kg.

Enhanced Driving with DKU Performance Exhaust Systems

The resonator delete carried out on this Audi A5 Exhaust System delivers a noticeable improvement in sound and flow without the need for a full system replacement. By removing the central resonator, back pressure is reduced and the natural tone of the engine is enhanced. The result is a deeper, sportier exhaust note, improved throttle response feel, and a more engaging overall driving experience, perfectly suited to the character of the A5.
