The Custom Muffler TCO3181 is a pure motorsport exhaust system engineered for the Toyota GR86 and Subaru BRZ.

Designed strictly for competition use, it delivers aggressive, high-decibel acoustics and a drastic weight reduction over the heavy OEM system. This high-flow, straight-through design prioritizes maximum performance and auditory feedback for closed-course driving, far exceeding all street-legal sound limits.
