KYOSTAR Catless Downpipes for Infiniti Q50 Q60 Nissan Z VR30DDTT 3.0T Twin Turbo

KYOSTAR Catless Downpipes for Infiniti Q50 Q60 Nissan Z VR30DDTT 3.0T Twin Turbo

Upgrade your Infiniti Q50, Infiniti Q60, or Nissan Z equipped with the VR30DDTT 3.0L Twin-Turbo V6 engine with the KYOSTAR Catless Exhaust Downpipe Kit. Designed to replace the restrictive factory downpipe sections, this performance exhaust upgrade provides a more direct exhaust path for improved flow and a more aggressive turbocharged exhaust sound.

The catless configuration eliminates the catalytic converter restriction within the downpipe section, helping exhaust gases exit the turbochargers more efficiently. Constructed from stainless steel with precision-formed piping and vehicle-specific mounting points, the system is designed for performance-oriented VR30DDTT applications.
