Get ready to experience unparalleled performance with the Thunderheader Long Style High-Performace 2-Into-1 Exhaust System with Heat Shields . This innovative exhaust system is designed to give you maximum horsepower without sacrificing low-end torque. The 2-into-1 system features a patented collector design that directs spent exhaust gases in a spiral motion through four acoustical damping chambers. Here, the exhaust travels at high velocity to scavenge spent exhaust gases from the combustion chamber, bringing in a fresh charge of air/fuel mixture. This not only improves horsepower and torque but also enhances throttle response. The anti-reversion design is critical for maintaining peak performance. It works by impeding reverse flow through the system. As reverse flow enters the collector, the diffuser deflects it through vents. The pyramidal trap and apertures then impede the reverse flow, allowing time for the exhaust valve to close. This ensures the incoming air/fuel mixture stays clean and free from contaminants, optimizing performance. The flow director has equal area at each end, allowing exhaust gases to travel at a constant velocity over the entire length of the system to improve exhaust scavenging. The net result is maximized engine performance and power. But performance isn't the only consideration - Thunderheader recognizes the importance of style and comfort. That's why this exhaust system includes a set of full-coverage heat shields, effectively preventing any discomfort or damage caused by contact with the hot exhaust.
