H-Pipe --- X-Pipe
X and H pipes have the same goal...to balance a true dual system and increase scavenging.
The X-pipe is really the best performaing solution for 6 bangers, and depending on design, most others as well.
It all started with the H - and then 'upgraded' to the X. There are better designs than others though...
