Thunderheader True Dual Exhaust System 4402702
Dennis Kirk Part #: 4402702
Thunderheader True Dual Exhaust System 4402702: Individual pipes for each cylinder. Furnished with fittings for Oxygen sensors. ThunderHeader head pipes have been tuned to the proper length and diameter to produce maximum horsepower and a excellent torque curve. A patented collector is used. The collector is designed to direct spent gases through four acoustical dampening chambers. The flow director serves a multi-task function: directs outgoing flow through four acoustical dampening chambers creating a spiral motion upon exiting to atmosphere and it also forms a pyramidal shaped anti-revision trap to minimize the amount of air rushing in. In conjunction with the flow director, a diffuser shroud is attached to the reverse cone, this patented device is designed to defuse the air rushing in as the pressure inside of the system becomes equal to atmosphere. , NOTE: Complete with heat shields.

H44022 Thunderheader 2-into-1 Long-Style Dual Falsee System
Dennis Kirk Part #: H44022
H44022 Thunderheader 2-into-1 Long-Style Dual Falsee System: Manufacturer part # 1025 - Designed to give maximum horsepower without sacrificing low-end torque. 2-into-1 systems with patented collector design that directs spent exhaust gases in a spiral motion through four acoustical damping chambers. Exhaust travels through these chambers at high velocity to scavenge spent exhaust gases from the combustion chamber and bring in a fresh charge of air/fuel mixture. Anti-reversion design works to impede reverse flow through the system -- reverse flow can contaminate the incoming fuel/air mixture, which reduces performance and throttle response. As reverse flow enters the collector, the diffuser deflects it through vents; the pyramidal trap and aperatures impede the reverse flow, allowing time for the exhaust valve to close. Flow director has equal area at each end, allowing exhaust gases to travel at a constant velocity over the entire length to improve exhauaust scavenging. For heat shields, order the following: H25-014 22" top front; H25-013 16" top rear; H25-030 28" collector. , , For the best performance, a free-flowing air cleaner and carb re-jet kit or adjustable fuel management system is recommended with this pipe. Dennis Kirk recommends a speed's performance speedyflow air cleaner for most models. See 18-3336 for 93-99 EVO carb models or 18-3337 for all twin cam models , NOTE: There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (blueing)is the result of tuning characteristics, cam timing, carburetor jetting, overheating,etc. and is not caused by defective manufacturing., , See lubrication products for products that will help prevent or remove blueing.. 1025
