Scorpion Cat/GPF-Back Exhaust System - Audi S3 (8Y) Sedan - 80mm
Scorpion's cat/GPF-back system for the Audi S3 (8Y) Sedan replaces the factory exhaust behind the GPF with 80mm (3.15") T304 stainless pipework and quad 114mm tailpipes. Scorpion lists the same part numbers for GPF and rest-of-world 8Y Sedans, and it connects to the OE front section or a Scorpion front pipe.

Scorpion exhaust sound test – Audi S3 8Y Sedan
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: polished Daytona stainless slash-cut tips; Daytona tips with a matte black ceramic coating; Ascari tips with a carbon fibre outer sleeve.
Note: All Australian-delivered S3 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.
