{"product_id":"3-0l-downpipe","title":"3.0L Downpipe","description":"The Milltek Sport Large-Bore Downpipe is engineered to significantly enhance both the performance and auditory experience of your Audi B9 RS4 or RS5. Fabricated with a larger diameter than the factory components, this downpipe provides increased space for exhaust gases to exit, thereby improving engine efficiency and power output. Used in conjunction with a catalyst bypass pipe, it offers substantial power gains by eliminating catalytic converter restrictions.\n\nConstructed from aerospace-grade type 304, non-magnetic stainless steel, this downpipe is built for durability and resistance to discoloration, ensuring a long lifespan. The use of mandrel-bent pipework guarantees consistent radius bends for optimized gas flow, while the enlarged bore diameters contribute to ultimate performance without sacrificing mid-range torque. Milltek Sport’s commitment to acoustic development ensures a sporty and crisp exhaust note, free from NVH, drone, or cabin resonance.\n\nThis product is specifically a decat and OPF\/GPF bypass unit. It requires a Stage 2 ECU remap to function correctly and achieve its performance benefits. Please note that the use of de-cat components is intended for off-road or motorsport use only, as they will inhibit the vehicle from passing a MOT test. Only EC type-approved components are legal for road use.","brand":"Milltek Sport","offers":[{"title":"Default Title","offer_id":52689144021304,"sku":"SSXAU820","price":290.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687385419.webp?v=1784902561","url":"https:\/\/store.motormia.co\/products\/3-0l-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
