This 3" catless race lower downpipe set is designed for selected Infiniti Q50, Infiniti Q60, and Nissan Z models equipped with the 3.0L VR30DDTT twin-turbo engine. It is a vehicle-specific lower downpipe / LDP set intended for the lower section of the VR30 exhaust system.
Built from stainless steel with mandrel-bent 3" tubing, this set is designed to provide a less restrictive exhaust path compared with some factory-style lower downpipe layouts. It is supplied with the gaskets and installation hardware shown with the product.
Selected VR30DDTT 3.0L twin-turbo applications.
Lower section only — not upper downpipes or a full downpipe kit.
Mandrel-bent tubing with vehicle-specific flange connections.
Designed for the lower downpipe section on compatible Q50, Q60, and Nissan Z VR30DDTT applications.
It is not an upper downpipe set, complete upper-and-lower downpipe kit, catback exhaust, or universal pipe kit.
