Product Overview
Upgrade your Infiniti Q50 with this 100% brand-new Extreme Online Store full cat-back exhaust kit, designed as a direct replacement for compatible 2017-present Infiniti Q50 2WD models. This system features a dual muffler delete design with resonated mid-pipe and Y-pipe kit for a complete lower rear exhaust upgrade.
Built for Q50 owners who want a cleaner rear-end appearance and a more assertive exhaust setup, this kit includes left and right axle-back dual tips, a 2.5-inch resonated mid-pipe tube, and a direct Y-pipe kit. It is not a universal-fit part and is intended for vehicle-specific installation.
The exhaust uses dual 4.5-inch round angle-cut tips with double-wall construction and an anodized silver finish. The system features 2.5-inch piping, including 2.5-inch mandrel-bent mid-pipe tubing, with a dual exit layout.
Constructed from T-304 stainless steel, this exhaust kit is built with hand-crafted high-quality TIG welding for a durable, performance-oriented structure. The anodized silver surface finish adds a refined look at the lower rear of the vehicle.
This bolt-on system is designed for direct installation with no cutting required. Gaskets, hangers, and mounting hardware are included, and professional installation is highly recommended for best fit and alignment.
Note: Fits 2017-present Infiniti Q50 2WD models as specified in the compatibility table. Does not work with aftermarket exhaust systems or Infiniti Q50 AWD models.
