Description
Unleash the true sound and performance of your 2023–2024 Nissan Z with the STILLEN Cat-Back Exhaust “Street Series” — the result of months of meticulous R&D, dyno testing, and craftsmanship. Designed and made in the USA, this cat-back system blends maximum performance gains with refined, aggressive sound that enhances your driving experience without going overboard.
During development, STILLEN engineers tested multiple configurations to perfect the balance between flow and tone. While a true dual setup proved too loud and flat-sounding for the Z’s twin-turbo V6, the optimal solution was a CNC-machined X-pipe — merging the banks without restricting airflow. The result? A richer, fuller exhaust note and smoother power delivery, all routed through TIG-welded 304 stainless steel from flange to tip.
Choose your finish: polished stainless, burnt stainless, or carbon fiber tips, and enjoy a bolt-on fitment that maintains a clean look while dramatically improving exhaust tone and efficiency. STILLEN’s in-house built mufflers feature proprietary manufacturing techniques and a weld finish that’s as much art as it is engineering. Best of all, the system is CEL-safe, keeping your check engine light off and your confidence high.
