Pro Circuit has always been known as a premier manufacturer of high-performance products for dirt bikes, but sometimes they find a new project to work their magic on like the new Grom by Honda and Kawasaki's new Z125 Pro. As unique and trick as those little bikes are, Pro Circuit knew they could make them better with their T-6 Exhaust System. Improved performance is the goal and the T-6 System hit the mark. Manufactured in the U.S.A. from durable stainless steel, titanium and carbon fiber materials, the T-6 System looks as good as it performs. Improves performance. Stainless steel construction throughout head pipe. Brushed aluminum canister. Carbon fiber end-cap. Strong mounting bracket for increased strength and durability. Asymmetrical muffler configuration for increased packing volume. Removable U.S.F.S. approved spark arrestor (off-road models ONLY). TIG precision welding.
