CB750 Crossover headers
« on: June 10, 2012, 09:07:17 AM »
I built these pipes for my chop. They are straight drags but can be built with collectors for 4-2 pipes that sound way different than what you're useed to. Cylinders 2&3 and 1&4 are paired together. This changes the firing order you hear from both sides of the bike, and aids in exhaust scavenging when collectors are used.
They look pretty cool too.

I'm making a few changes to the next set and will be fixturing them for production.
