Manufacturer: Thunderheader
Dennis Kirk Part #: H44009
Thunderheader 2 into 1 High Performance Exhaust System: Manufacturer part # 1011 - 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 apertures 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 exhaust scavenging. For heat shields, order the following:, 13 in. Top Front - H25-026, 19 in. Top Rear - H25-015. For Sportster models with forward controls. For models without forward controls use part number H44-010. , 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.. 1011
