STILLEN 2023-2026 Nissan Z Cat Back Exhaust "Competition Series"

The STILLEN Competition Series Cat-Back Exhaust for the 2023–2026 Nissan Z [VR30 Twin Turbo V6] is engineered for maximum performance, sound, and visual appeal. Designed specifically for the twin-turbo VR30 engine, this straight-pipe exhaust system eliminates mufflers for an aggressive, track-inspired tone while still optimizing airflow and exhaust scavenging.

Crafted from 304 stainless steel with precision TIG-welded flanges, CNC-bent and machined X-pipe, and multiple tip finish options (polished, burnt, or carbon fiber), this system is built for both performance and durability. A STILLEN-branded reinforced cross-brace provides added support and a show-quality look for the rear undercarriage.

Through extensive dyno testing and in-house R&D, STILLEN’s engineers optimized the design to ensure no flow restriction while maximizing exhaust sound, making this system ideal for drivers who want to hear every note of their twin-turbo V6.
