STILLEN 2009-2015 Nissan Maxima Cat-Back Exhaust System - 504396

The STILLEN Cat-Back Exhaust System for the 2009–2015 Nissan Maxima [A35] is engineered to maximize performance, enhance sound, and elevate the overall appearance of Nissan’s 7th-generation sport sedan.

Built from high-quality stainless steel, this complete cat-back system improves exhaust flow to deliver a maximum increase in horsepower and torque, while maintaining excellent drivability. At idle and during cruising, the exhaust produces a mild, refined tone, but under throttle it transforms into an aggressive, sporty exhaust note that brings the VQ35 engine to life.

Drawing from decades of experience tuning Nissan’s VQ platforms, STILLEN designed this system to complement the factory exhaust cut-out locations while providing a bold visual upgrade with polished dual-wall exhaust tips. Whether your priority is performance, sound, or appearance, this cat-back exhaust delivers on all fronts.

The system is fully bolt-on, requiring no cutting or welding, and is backed by STILLEN’s Limited Lifetime Warranty for long-term confidence.
