Show original supplier description
The Supersprint 816721 is a performance turbo downpipe kit that includes a metallic catalytic converter, designed for enhanced exhaust flow and power output. This unit is equipped with a threaded boss to accommodate an O2 sensor. Designed with competition in mind, this downpipe kit is strictly reserved for racing applications and is not street-legal. It is explicitly stated that this product is not compatible with the original catalytic converter, indicating it's a full replacement system component. Installation of this downpipe requires specific accompanying parts from Supersprint: it must be mounted in conjunction with part numbers 816712 and either 816003 or 816013 to form a complete system. This product is listed as compatible with the Fiat 500 U.S. Model (135 hp) from 2015 onwards.
