Infiniti Q50/Q60 VR30DDTT 3.0" Catted Downpipes

The PLM Infiniti Q50/Q60 Full Downpipes Kit is engineered to significantly enhance the performance of VR30DDTT engines. The system features 3.0" mandrel-bent piping that tapers to a 2.5" outlet, promoting improved exhaust flow and reduced backpressure. Central to the performance gains are the integrated 200-cell high-flow metallic catalytic converters, designed to increase horsepower and torque. Estimated gains are substantial: +50–60 HP for 300 HP models and +25–35 HP for 400 HP models. These downpipes are compatible with both factory and most aftermarket cat-back exhaust systems. Installation is streamlined thanks to the OEM-style V-band fitment, which allows for a direct bolt-on application without requiring modifications to the vehicle. The kit reuses factory V-band clamps and utilizes OEM mounting tabs, ensuring a factory-like fit. Included are J-style O2 sensor adapters (eliminating the need for wiring extensions), all necessary hardware, and gaskets. This downpipe kit is specifically designed for the 2015+ Infiniti Q50 Sedan and the 2017+ Infiniti Q60 Coupe, all equipped with the VR30DDTT engine. It fits all trim levels and is compatible with both RWD and AWD models. Note that this product is designed exclusively for VR30DDTT engines.
