Ferrari F355 Exhaust

The Sound

Replacing the stock catalysts with HJS HDPE motorsport catalysts, or de-cat pipes, opens up the sound significantly. On valve open, the silencer is completely bypassed, and the exhaust discharge is merged into a Y pipe, blending the exhaust gases 180 degrees out of phase, resulting in a higher pitched sound. On valve closed, the gases are diverted through a series of chambers, and acoustic fill sections, resulting in a smooth and unobtrusive sound when cruising.

Equal length headers complement the exhaust perfectly, and enrich that F1 scream!
