STILLEN 2016-2018 Nissan Maxima Cat Back Exhaust - [3.5L] - 504398

The STILLEN Cat-Back Exhaust System for the 2016–2018 Nissan Maxima [A36] 3.5L is engineered to enhance performance, sound, and visual appeal while maintaining daily-driver refinement. Designed specifically for the 8th-generation Maxima, this exhaust delivers increased horsepower and torque to the wheels with a tone that stays mild during idle and cruising, then turns aggressive under throttle.

Constructed from 304 stainless steel, this cat-back system features a precision-tuned Y-pipe, signature STILLEN resonator, and dual mufflers to maximize exhaust flow while controlling unwanted drone. The system exits through dual polished 4-inch angle-cut tips, pre-welded to the mufflers for perfect alignment with the factory exhaust cut-outs.

This exhaust is a direct bolt-on system, making installation simple enough for a driveway or garage install. Backed by a Limited Lifetime Warranty, the STILLEN cat-back exhaust delivers long-term durability, signature sound, and proven performance.
