2014–2025 Infiniti Q50 Exhaust FAQ's

Please read our FAQs page to find out more.

How do I add sound without drone on a Q50?

A quality cat‑back with proper muffler volume and a resonator deepens tone while controlling rasp/drone for daily use.

Catted vs catless downpipes on the VR30—what’s smarter?

High‑flow cats support power while controlling odor and rasp. Catless flows more but may be emissions‑noncompliant; check local laws and always tune.

Do I need a tune after downpipes or headers (VQ37)?

Yes—post‑exhaust changes affect fueling and trims. A calibration restores targets, controls CELs, and protects the engine under load.
