STILLEN is excited to release the cat-back exhaust system for the 2023 Nissan Z. During the development of this exhaust system STILLEN engineers went through multiple different exhaust configurations and prototypes determine what would provide the best performance, best flow, and best sound.

The Competition Series Cat-Back Exhaust for the Nissan Z is intended for the owner that wants to be heard. With no mufflers, this straight piped system is aggressive and allows the NISSAN VR30 twin turbo V6 engine to be experienced. STILLEN’s R&D team decided to move forward with the competition series exhaust because a common character trait of twin turbo engines is that the turbos suppress the exhaust tone and many people do want a more aggressive exhaust sound. The competition series exhaust from STILLEN offers all of the benefits of an engineered, tested, and performance designed exhaust system at a low cost with a more aggressive tone than a system featuring mufflers.
