Fabricating a set of custom headers for your performance vehicle? Bring all the primaries together with header collectors!
Also called merge collectors, these pipes transition the primary header tubes from each cylinder together to a single tube. This can help with the scavenging effect, as exhaust pulses passing through the collector help pull gasses out of the other primaries, increasing the efficiency of the engine. For more information on collector designs and how they affect performance, check out this article on our official blog. Also, check out header reducers here.
