UNLEASH THE TRACK-DAY POTENTIAL OF YOUR TURBO CIVIC WITH RACE-FOCUSED SOUND AND WEIGHT SAVINGS.

The Custom Muffler HCO3143 is a competition-only stainless steel exhaust system engineered for the 1.5L Turbo Honda Civic (FL1).

Designed strictly for motorsport use, it delivers an aggressive, high-decibel exhaust note, substantial weight reduction, and a focused single-exit design—unlocking a more raw performance character for the L15C engine in closed-course environments.
