This premium collection unit features an improved setup point and a stainless steel 4-2-1 exhaust manifold with optimised equal-length runners. The expanded secondary pipe diameter, along with flanged and pipe insert couplings, are all precision TIG welded. These design elements, combined with careful polishing work, significantly reduce exhaust interference. As a result, this manifold delivers noticeable torque improvements in the mid-range RPM region.
