Features and Benefits Of This Product

  • This race down pipe uses a unique resonance chamber to capture sound waves and minimize in-cab resonance producing an aggressive tone on throttle with a smooth sound at cruising speeds without effecting performance.
  • In recent testing, the race version down pipe produced +14 horsepower and +39 lbs. x ft. of torque.
  • The high-flowing down pipe is designed using mandrel-bent, 304 stainless steel tubing for optimum flow resulting in added horse power and torque.
  • The down pipe is 100% hand TIG-Welded and uses a 3-1/2" into 4” stepped design that increases exhaust velocity and eliminates low pressure drops which helps to scavenge the exhaust for increased intake charge and more power.
  • This down pipe is designed using a resonance chamber to help reduce the in-cab resonance found with other non-catted down pipes.
  • A unique 3.5" to 4" stepped design, is used to increase exhaust velocity and increase usable torque. This means more aggressive throttle response and increased passing power.
  • 100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.
