2023–2025 Acura Integra Type S Exhaust FAQ's

Please read our FAQs page to find out more.

What exhaust diameter works best on the Type S?

A 3.0" cat‑back supports strong flow and a deeper tone without excessive drone. Pair with a high‑flow catted downpipe for power and compliance.

Do I need a tune after a downpipe on the Type S?

Yesβ€”post‑turbo changes affect boost control and fueling. A calibration restores AFR targets and protects the engine under load.

Catted vs. catless on the Integra Type Sβ€”what’s smarter?

Modern high‑flow cats support power while controlling odor and rasp. Catless can be louder and emissions‑noncompliant; check local laws.
