Reducing backpressure at this point in the exhaust system typically delivers one of the most noticeable power and response gains available on a turbocharged platform, particularly when paired with a supporting ECU tune.\u003c\/p\u003e\u003cp\u003eThis version retains genuine catalytic converter function via a high-flow sports cat, a sensible middle ground for those wanting improved flow while staying closer to factory emissions compliance than a full de-cat pipe.\u003c\/p\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eAudi RS3 Saloon\/Sedan 400PS (8V MQB)\u003c\/li\u003e\u003c\/ul\u003e","brand":"Milltek Sport","offers":[{"title":"Default Title","offer_id":54638948909389,"sku":"SSXAU726","price":1898.48,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/i6tuning.com\/products\/milltek-audi-rs3-saloon-400ps-8v-downpipe-hiflow-cat","provider":"i6 Tuning","version":"1.0","type":"link"}
