Audi TTS (Mk2 8J) Quattro 3" Downpipe/Front Pipe – Sports Cat or Decat (Catless) Performance Exhaust, Turbo Outlet to OEM Centre Section, Coupe/Roadster, High-Flow Cat, Cat Delete, Stage 2 Bolt-On Upgrade, 76.2mm

Audi TTS Mk2 Quattro Down Pipe Upgrade with Sports Catalyst or Decat

Unlock the sound and flow your TTS deserves with this precision-made front pipe assembly, engineered to run from the turbo outlet to the factory centre section. Built in free-flowing 3 inch 76.2 mm pipework, it is designed to reduce restriction, amplify the turbo soundtrack and complement further tuning while retaining straightforward, bolt-on compatibility with the original cat-back.
