Discover the Akrapovic Audi S3 Sedan (8Y) Evolution Line S-AU/TI/18H

The Akrapovic Audi S3 Sedan (8Y) Evolution Line S-AU/TI/18H exhaust system is crafted to deliver an instant performance upgrade, a distinctive exhaust tone, and a significant weight reduction. Designed using race-proven materials—titanium for the muffler and link pipe section, plus carbon fibre for the newly styled dual tailpipes—this system is remarkably 41% lighter than the factory setup. Tested and verified on the Akrapovič dyno against a standard S3 exhaust, it provides an extra 4 kW (5.4 hp) at 4,350 rpm and a torque gain of 8.8 Nm at 3,900 rpm, all while meeting the requirements of an ECE type-approved design for cars equipped with an Otto/gasoline particulate filter.

Key Features of S-AU/TI/18H

An immediate standout of the Akrapovic Audi S3 Sedan (8Y) Evolution Line S-AU/TI/18H is its innovative valve system. Manufactured in Akrapovič’s own foundry, the valve housing sits outside the muffler to optimize gas flow and sound regulation. This clever design choice allows for a smooth and rich note during normal cruising, effortlessly transitioning into a deeper, sportier tone when you demand more from the Audi S3. There’s no intrusive drone in the cabin, so you can relish the new exhaust character without sacrificing everyday comfort.

Additionally, each hand-crafted carbon-fibre tailpipe adds both visual flair and functional heat resistance. These tailpipes highlight the brand’s meticulous craftsmanship and underscore the sporty aesthetic of the S3 Sedan (8Y). Beyond style, the use of titanium in the muffler and link pipe sections ensures excellent durability and heat management, making this system as reliable as it is performance-focused.

Performance Gains and Driving Experience

Built to enhance the S3’s spirited personality, the Akrapovic Audi S3 Sedan (8Y) Evolution Line S-AU/TI/18H significantly improves throttle response and mid-range torque delivery. You’ll notice the +4 kW (5.4 hp) at 4,350 rpm whenever you accelerate, while the +8.8 Nm torque jump at 3,900 rpm provides more punch out of corners and during highway merges. Thanks to the lighter overall construction—shedding 8.9 kg (19.7 lb) from the stock exhaust’s 21.6 kg—you also benefit from more agile handling.

These power and torque figures make a real difference in everyday driving, giving you an audible and tangible reminder of the S3’s performance potential every time you push the pedal. The new exhaust note—deeply resonant under load yet mellow when cruising—blends seamlessly into the driving experience, whether you’re heading to work or exploring twisty back roads on the weekend.
