Common Questions Related to this Mod

Related FAQ answers that may help before you buy or install.

engine / intake / exhaust

Do I need a tune for an axle-back or cat-back exhaust on the 2022+ WRX?

No. Both sit behind the catalytic converter, so neither changes what the ECU measures. Fit one and drive - no tune, no check engine light, and almost no power either.
