Description

The STILLEN Cat-Back Exhaust system is engineered to enhance the performance and sound of your 2016-2024 Nissan Titan (non-XD) equipped with the 5.6L engine. This system features a dual mandrel-bent 2.5-inch stainless steel tubing construction that flows into a single, performance-tuned muffler. The exhaust exits through a 3-inch pipe, culminating in a stylish 4-inch black dual-wall engraved tip, showcasing the STILLEN branding. Constructed from durable stainless steel, this cat-back exhaust is built to last and is protected by a limited lifetime warranty. The system aims to deliver noticeable performance gains, with the manufacturer claiming an increase of up to +43 WHP at 4,100 RPM and +61 TQ at 3,800 RPM. This exhaust system is specifically designed for the 2016-2024 Nissan Titan models (excluding the Titan XD). It fits both 2WD and 4WD configurations.
