Milltek is out in front again with the impressive downpipes and cats for the new 4.2 V8 S4. Bolts-in directly to your exhaust manifolds. Replaces your OEM primary cat with a 200-cell platinum-coated metal high-flow cat and eliminates your OEM secondary cat. Power gains come when you can free up flow as close to the engine as possible and Milltek delivers. Dyno proven to deliver 20 lb-ft and 15hp at the wheels. When combined with the Milltek catback your S4 jumps by 40 lb-ft and 30hp at the wheels. More torque, more power, more growl. An unbeatable combination for the spectacular 4.2 V8 S4 from Milltek.
FITMENT: Audi S4 (B6/B7) 2004-up
