Supersprint already has the 2018 AUDI RS3 covered, offering several performance, full exhausts for the 400 Hp, latest generation 5 cyl. engine.

These Supersprint exhausts are available to the public since December 2017.
Our systems include a straight-through, smooth-bend oversized Turbo Downpipe, which eliminates the restriction of the stock catalytic, guaranteeing a massive drop in exhaust gas backpressure, and a substantial gain in torque and max Hp.
We then designed a twin pipe exhaust, equipped with a set of HJS Motorsport, high flowing twin, parallel metallic cats (Y-pipe also available in a cat-deleting version).
The rear muffler uses Supersprint's own, precision-built exhaust flaps, for dual-sound mode.
Furthermore, we have also developed a single pipe, lightweight race exhaust, built with 80mm piping, FIA compliant, for trackdays.
The Supersprint full exhausts are sized to complement engine modifications and software upgrades of 450 + Hp.
Installation and fitment are spot-on, as usual.
