DESIGNED WITH SOUND IN MIND

Concept841 uses equal lengths and a single collector to create a uniform exhaust pulse that produces the distinct sound of an even-firing engine. The collector recieves an exhaust pulse every 90 degrees creating continuous scavenging, further amplified by a smaller collector volume.

Simply Put: Its All About Balance.
