exhaust headers

  • Many other engine changes were made, including the use of a factory exhaust header.
  • In addition a balance tube has been added between the exhaust headers to smooth out power delivery.
  • Yamaha also designed a new exhaust pipe design so that exhaust header removal would no longer be required when replacing the oil filter.
  • Some of this is achieved by less aggressive engine internals and the "low boy" exhaust header pipe.
  • The length of exhaust headers can be tuned to perform best at specific RPM ranges.
  • A variable-length inlet manifold was used claimed to improve torque output, equal length stainless steel exhaust headers remains.
  • This resulted in new exhaust headers, new pistons, a new intake manifold, as well as new turbochargers.
  • The exhaust header stack turned upward, projecting above the top of the fuselage.
  • Some modern exhaust headers are available with a ceramic coating.
  • Another feature differentiating the three-cylinder GT models from their competitors was the bifurcation of the centre cylinder exhaust header.
  • The engine was also difficult to service, in part because its exhaust headers were on the inside of the cylinder banks, the reverse placement of most V-type liquid-cooled engine designs.
  • The goal of performance exhaust headers is mainly to decrease flow resistance (back pressure), and to increase the volumetric efficiency of an engine, resulting in a gain in power output.
  • They are specifically designed to reduce heat loss from engine exhaust system components including exhaust manifolds, turbocharger casings, exhaust headers, downpipes and tailpipes.
  • This allowed large bore exhaust header pipes (for excellent gas flow at high engine speeds) coupled with the valve restricting flow at lower revs, to speed the gas through.
  • The design could be modified for high performance by porting (in particular siamese) and isolating the inlet manifold from the exhaust header.
  • The exhaust itself was unusual for the time in that the centre exhaust header was split in two and exited into two mufflers much smaller than the single mufflers supplied for the two outboard cylinders.
  • From November 1976 this was changed to a single outlet exhaust header to comply with EPA regulations.
  • Switching from an exhaust manifold to exhaust headers (also known as extractors in Australia) will optimize the exhaust gas flow speed and in turn increase the high-end power of the engine.
  • The 4-2-1 design of the exhaust header shifts the power band slightly to the left of the normal engine power band, thereby providing higher output at middle-range rpm.
  • Rusted out exhaust headers or lengthy periods of turning the starter can cause water to build up in the exhaust line to the point it back-flows through the exhaust manifold and fills the cylinders.
