Turner meticulously designed their N55 downpipe inhouse to maximize flow, eliminating restriction and increasing power. Turner's high flow catted downpipe allows your N55 to produce more power, more torque, and a great sound. Turner's precision designed downpipe upgrade features larger piping and a sport catalytic converter for increased flow and reduced backpressure. Removing exhaust restrictions caused by the stock catalytic converter allows your turbo to spool faster down lower in the power band. Tuning is required to keep emissions fault codes and check engine lights from appearing, and it also allows you to get the most out of your new Turner catted downpipe - we recommend Turner's N55 tune: ES#3646920
