Cat-Back Exhaust System

The Stillen 508310 is a stainless steel cat-back exhaust system specifically designed for the 2013-2015 Nissan Altima 3.5L Sedan [L33]. Users can expect a refined driving experience with a sound profile that is mild during idle and cruising, yet delivers an aggressive note when accelerating. The system is crafted with a focus on both performance and aesthetics, featuring polished stainless steel tips, end pipes, and mufflers that complement the factory exhaust cutout and enhance the vehicle's rear appearance. Constructed from durable stainless steel, this cat-back system is built for longevity and resistance to corrosion. Beyond the performance enhancements, the Stillen exhaust system is noted for its ability to contribute to a more luxurious and quiet cabin feel when not under load, while still providing an engaging sound under throttle. This balance makes it a suitable upgrade for drivers seeking both enhanced performance and a refined auditory experience. The system includes everything needed for a complete installation as a cat-back unit.
