Overview of Thunderheader Racing Products X-Series Exhaust System - 1074X

  • The new Thunderheader™ X-Series™ for Touring is our large diameter exhaust specifically designed for big cubic inch engines, built to produce big numbers
  • The X-Series™ is designed with 2 in. primary tubes with a 14 degree transition chamber to allow more exhaust flow
  • Unique patented baffle in conjunction with the trademark tail cone is designed to allow a free flowing exhaust while creating an anti reversion condition in the pipe which will aid the air/fuel flow on the intake stroke to allow more fuel into the combustion chamber
  • This means more torque at the low and mid RPM ranges and maximum horsepower at top end
  • The X-Series™ comes complete with heat shields and all mounting hardware, and both 12mm and 18mm O2 sensors
  • O2 sensor ports are pre-installed with O2 sensor plugs

There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (bluing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing. See the CHEMS/LUBES section in the back of this catalog for products that will help prevent or remove bluing.

Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that may need to be made during. or after, installing their product. If a jet kit or fuel processor is recommended, see the FUEL/INTAKE section
