Made entirely from Japanese Titanium, this handcrafted exhaust guarantees reduced weight and optimized gas expansion capacity for Big Bore setups over 70-85cc.
The low-mount design is engineered to maximize performance on very high-performance engines, improving top-end power and the ability to maintain power at high revs. Titanium, besides being completely corrosion-resistant, offers superior heat dissipation compared to steel, keeping performance consistent even under prolonged stress.

PRO TUNER NOTE:
On 86cc - 94cc setups, this titanium expansion chamber pushes power to extremely high revs, offering superior top-end and a much wider over-rev range compared to traditional exhausts. To get the most out of it, it is essential to pair it with large-diameter carburetors, racing ignitions, and precise ignition timing tuning.
