2023–2025 Nissan Z Exhaust FAQ's

Please read our FAQs page to find out more.

How do I add sound without drone on the RZ34?

A resonated cat‑back with proper muffler volume deepens tone while controlling rasp. On tuned cars, downpipes with high‑flow cats further improve response.

High‑flow cats vs catless on a turbo Z—pros and cons?

High‑flow cats cut backpressure yet manage odor/rasp; catless flows more but may be emissions‑illegal. Always verify local laws and tune fueling accordingly.

Do downpipes require a tune on the VR30?

Yes—exhaust changes affect load and fueling. A proper calibration optimizes trims, boost control, and torque limits while protecting the engine.
