AUDI S3 8V Cabrio QUATTRO 2.0 TFSI (300 Hp - models with GPF) 2019 -> 2020 Twin Pipe (with valve)

The most recent Euro regulations on the emissions are not kind to the performance and the sound of the latest generation models.

The 2019 Audi S3 Quattro Cabrio 2.0TFSI has a horribly restrictive exhaust, which uses a catalytic + GPF (Gasoline Particulate Filter) at the same time.

This new oem exhaust really wreaks havoc on the torque and peak hp, chocking the engine so bad, that the Hp rating from the Audi Factory has stepped from 310 Hp of the previous version down to 300 Hp.

On our in-house, Maha 4x4 dynometer we have measured even less power, 295 hp only.

Wasting no time, we immediately designed a full system, starting from the turbo back.

This is where the real horsepower and the torque increase are hiding.

Our plain approach is eliminating the stock catalytic and the GPF altogether, replacing them with a straight-through Turbo Downpipe, and a set of high flowing, HJS Motorsport catalytics, positioned further downstream, farther away from the engine.

With the Supersprint twin-pipe exhaust in place, the power jumps from 295hp to 321hp, no other modification added.

Eliminating the restrictions leads  to a reduction of the  heat soak, and to an easier spooling of the Turbo, uncovering the full potential of 400 hp with the only addition of the same software tunes that were so popular on the previous, non-GPF version.

No less important, the Supersprint full system guarantees a magnificent sound, with lots of burbling, bangs at pops; yet no droning inside of the cabin.
