Product Description

The Invidia HS14IQ5GIS Gemini Cat-Back Exhaust delivers a high-quality, bolt-on performance upgrade for 2014-2022 Infiniti Q50 sedans (RWD and AWD). Constructed from SUS304 stainless steel with mandrel-bent 60 mm piping and polished dual tips, the system significantly improves exhaust flow, delivering a deeper, sportier exhaust note and better throttle response without a harsh cabin drone.

Precision-machined flanges, robot-TIG welds, and polished finish ensure durable, leak-free installation that integrates cleanly with stock underbody hangers -- no cutting or fabrication needed. Whether you drive a 2.0T, 3.0T, 3.7L, or Hybrid Q50 within the 2014-2022 production run, HS14IQ5GIS offers a great balance of performance, sound, and reliability. For 2023 and newer Q50s, due to unverified layout changes, fitment must be double-checked before purchase or install.
