Description
Rather than treating the 2016-2024 Infiniti Q50 (Auto V6) - 4.5in as a universal exhaust application, Borla engineers this configuration around the vehicle's specific layout and intended fitment. The role of this cat-back exhaust system is straightforward: it reworks the exhaust downstream of the catalytic-converter section for a broader change in tone, flow character, and rear-of-car presentation.
It is a strong fit for an owner who wants the exhaust upgrade to feel complete—sound, visible finish, and the character of the system behind the catalytic-converter section—rather than changing only the rear mufflers. In practice, this product is best suited to owners who want to bring more mechanical character to a performance-oriented luxury platform while retaining a finished, vehicle-specific presentation.

About Borla
Borla's background is rooted in American performance exhaust engineering, with decades spent developing vehicle-specific systems that balance sound, fitment, and long-term durability. That background makes this product a natural choice for a build where exhaust tone and fitment matter as much as simply replacing factory hardware.
Fitment note: Confirm model year, engine, trim, factory exhaust equipment, and the selected Borla part number before ordering.
