STILLEN 2016-2018 Nissan Maxima Axle Back Exhaust System - 504399

The STILLEN Axle-Back Exhaust System for the 2016–2018 Nissan Maxima [A36] 3.5L is designed for drivers who want improved sound and appearance without sacrificing cabin comfort. Engineered using STILLEN’s decades of experience with Nissan’s VQ35 3.5L V6, this axle-back system delivers gains in horsepower and torque to the wheels while maintaining a refined, luxury-friendly interior sound level.

This system produces a mild note at idle and cruising, transforming into an aggressive exhaust tone under throttle, making it ideal for daily-driven Maximas. Compared to a full cat-back system, the axle-back offers a more budget-friendly solution with reduced interior noise—perfect for those who want enhanced sound without drone.

Constructed from stainless steel, the system features dual mufflers with pre-welded 4-inch angle-cut, dual-wall polished tips that fill the factory exhaust cut-outs perfectly. The result is a clean, aggressive rear appearance that complements the Maxima’s styling.

Backed by a Limited Lifetime Warranty, the STILLEN axle-back exhaust delivers durability, sound refinement, and unmistakable STILLEN quality.
