Product Description

The Remark RO-TSQ5-S Axle-Back Exhaust is a direct bolt-on rear exhaust upgrade designed for the 2014 through 2024 Infiniti Q50 (V37), compatible with both rear-wheel drive and all-wheel drive variants. Constructed from 2.5" mandrel-bent T304 stainless steel and finished with polished stainless single-wall 4.5" tips, this axle-back replaces the factory muffler section to improve exhaust flow and provide a more assertive, sporty tone while reducing overall weight. Installation uses the existing OEM hanger rods and includes all required gaskets and hardware.

Engineered to work with the factory or Remark mid/piping, the RO-TSQ5-S does not fit aftermarket exhaust systems without modification. Its straight-through muffler delete design enhances sound character and exhaust presence without requiring a full cat-back system, making it a cost-effective way to add a more engaging exhaust note to your Infiniti Q50.
