The Army SX 70-80cc exhaust works very well with 70 to 80cc kits such as the Metrakit Pro Race 70cc, Malossi 80cc, Airsal Xtreme 80cc, Bidalot 70cc, Airsal 70 Fonte or Alu... We have worked the exhaust to have some low-end torque and immediate engine response, while maintaining high revs ideal for all-day riding. It is made of hand-welded rolled sheet steel and comes with an Army Black silencer.
