Scorpion Cat/GPF-Back Exhaust System - Audi RS3 (8Y) Sedan - 80mm
This Scorpion cat/GPF-back system replaces the factory exhaust behind the GPF on the Audi RS3 (8Y) Sedan. It runs 80mm (3.15") T304 stainless pipework to a rear silencer and is offered with 170 x 120mm Ascari RS carbon fibre tailpipes or with OE-fitment outlets that keep the factory tailpipe trims. Scorpion lists the same system for GPF and non-GPF (rest-of-world) 8Y Sedans, and it fits the OE front section or a Scorpion front pipe.

Audi RS3 8Y with Scorpion exhaust – road test
Resonated versions keep a centre silencer for a deeper, more refined tone with less cabin drone; non-resonated versions replace it with straight pipe for a louder, rawer note. Valved versions retain the factory exhaust flaps (they reuse the OE valve motors), so the car can still switch between quiet and loud modes; non-valved versions delete the flaps and stay open all the time, which makes them considerably louder. Tailpipe choices: Ascari RS tips with a carbon fibre outer sleeve, or OE-fitment outlets that work with the factory tailpipe trims.
Note: All Australian-delivered RS3 8Y models have a GPF; Scorpion lists this system for GPF cars. Valved versions need the OE valve motors. Installation by a professional is recommended.
