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?

Yes—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 S—what’s smarter?

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