PLM Infiniti Q50 / Q60 VR30 Catted Full Downpipes Kit (2016–2023)

SKU: PLM-V37-DP-CAT

Product Description

The PLM Private Label Mfg. Catted Full Downpipes Kit for the Infiniti Q50 and Q60 VR30 (2016–2023) is engineered to deliver substantial power gains while maintaining drivability and emissions control. Designed specifically for the VR30DDTT twin-turbo platform, this system dramatically improves exhaust flow by replacing the restrictive factory downpipes with high-quality, high-flow components.

Featuring 3.0-inch mandrel-bent stainless steel piping that transitions to 2.5 inches at the outlet, these downpipes maintain optimal velocity while reducing backpressure. The integrated 200-cell metallic high-flow catalytic converters strike the perfect balance between performance and refinement, making this kit ideal for both street and performance-focused builds.

For seamless installation, PLM utilizes OEM-style CNC-machined V-band flanges, allowing the downpipes to bolt directly to factory turbos while reusing the original V-band clamps. Precision TIG welding, OEM mounting tabs, and included hardware ensure a factory-like fit with aftermarket performance benefits.

On tuned setups, expect gains of 50–60+ horsepower on 300hp models and 25–35+ horsepower on 400hp models, making this one of the best value upgrades available for the VR30 platform.
