The high-quality of Yoshimura Exhaust Systems and Slip-On Mufflers are a direct result of the company’s commitment to uncompromising quality standards, extensive research, and development, unrivaled expertise in manufacturing. The Hepta Force is designed for larger displacement bikes that need more volume. This adventure muffler uses only the finest materials and emits the most glorious sound from the KTM 1190 Adventure. Hepta Force gives the big twin engine a deep thunder sound while on the gas, yet is still ear-pleasing while at low RPM. Power and torque are increased while weight is dramatically reduced from the stock muffler.

  • 5.8 lbs (2.63 kg) -7.8 lbs (-3.54 kg) lighter than stock!(compare to titanium Akropovic at 9 lbs and over $1000)
  • Available with stainless mid-pipe, titanium sleeve with a carbon fiber end cap; but don't let this beauty fool you, it's a mighty workhorse for the KTM 1190. 
  • Distinctive Hepta Force shape maximizes muffler capacity
  • Seven sided titanium canister is ultra-light and ultra-durable
  • Polished stainless steel front inlet
  • Unique carbon fiber end cap
