2014-2024 Infiniti Q50 Axle-Back Exhaust
This axle-back system is built for the 2014-2024 Infiniti Q50 sedan. It replaces the factory rear muffler section and bolts to the factory mid-pipe flanges, leaving the stock catalytic converters and mid-pipe in place. Both the main piping and the tips are made from T201 stainless steel, and the system exits through dual 4-inch slant-cut tips.

Bundled Option — Axle Back + L&R Catalytic Converters: This option pairs the axle-back system with left and right catalytic converters for 2014-2015 Infiniti Q50 3.7L V6 models. It is sold as a separate variant and is not included with the standard Axle Back option.
Key Features
- Two-Piece Axle-Back Layout: The left and right sections replace the factory rear muffler section and connect to the stock mid-pipe flanges, so the install is contained to the rear portion of the exhaust.
- T201 Stainless Steel Piping and Tips: The main piping and the tips are both built from T201 stainless steel, so the visible system uses one consistent material.
- 2.4 in Mandrel-Bent Main Piping: Mandrel bending keeps the 2.4 in bore consistent through the curved sections instead of letting it collapse at the bends.
- Dual 4 in Slant-Cut Tips: Two 4-inch slant-cut tips are welded to the piping and align with both rear bumper outlets for a balanced, symmetrical rear view.
- Keeps the Factory Catalytic Converters and Mid-Pipe: This system mounts behind the stock converters and mid-pipe, so no catalytic converter or mid-pipe replacement is needed for the install.
What's Included
- Two-piece axle-back exhaust assembly (left and right sections)
- 4 in slant-cut stainless steel tips, welded to the piping
Check Before Ordering
- Confirm your Q50's year, engine, and drivetrain against the Fitment chart above before placing your order.
- This system keeps the factory catalytic converters and mid-pipe. The standard Axle Back option does not include catalytic converters.
- The bundled Axle Back + L&R Catalytic Converters variant is limited to 2014-2015 Q50 3.7L V6 models; select it only if your vehicle matches that configuration.
- Since included hardware is not itemized on this page, check whether new gaskets or clamps are needed for your factory mid-pipe connection before you start the install.
