The kooks off road connection pipes neck down to 2.75.... so just cut it at the reducer, that way it stays 3" the whole way. Put the speed engineering pipes up and cut where they overlap.... then weld together. They have the same bends, so it's pretty selfexplanatory. Iirc, the speed engineering pipe gets cut right after the o2 bung, because I was hoping to use it for my wideband, but had to cut it out
