THUNDERHEADER Black Long Style High-Performance 2-Into-1 Exhaust System with Heat Shields – 1024SB

Thunderheader Black Long Style High-Performance 2-Into-1 Exhaust System with Heat Shields – 1024SB

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
