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!
Available in 100 cell, or 200 cell, HJS HDPE motorsport catalysts, or de-cat pipes for optimum sound and performance.
Manifold primaries 41mm, secondaries 57mm.
Rear section, valve open transit quad 57mm, valve closed transit, dual 57mm.
