Scorpion Cat/GPF-Back Exhaust System - Audi S3 (8V) 3 Door / Sportback - 80mm
Scorpion's cat/GPF-back system for the Audi S3 (8V) 3-door and Sportback replaces the factory exhaust from the catalyst rearward. It uses 80mm (3.15") T304 stainless pipework and quad 101mm tailpipes, and Scorpion lists the same system for pre-facelift, facelift non-GPF and facelift GPF cars. It fits the OE front section or a Scorpion front pipe.

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: Australian-delivered S3 8V models have no GPF; this system suits them. Valved versions need the OE valve motors. Installation by a professional is recommended.
