SF90SS-DP130Optional: choose oneRedstar Stainless Steel HJS HD 200CPSI 130 mm Downpipes for Ferrari SF90 (F173)
Redstar's SF90 downpipes are a direct bolt-on replacement for the factory downpipes on the Ferrari SF90 Stradale and SF90 Spider (F173) from 2019 on, with the 4.0-litre twin-turbo engine. Redstar also lists the 2024 SF90 XX. Redstar states the downpipes free up exhaust flow for faster turbo spool and better throttle response, reduce under-bonnet temperatures and add tone to the exhaust. Each assembly is 100% TIG welded and back purged, with OEM-spec CNC machined flanges and all brackets and mounts as on the factory unit.
