My brother-in-law bought his Valk new and put Two Brothers 6-6 pipes put on. He said with the Two Brothers he did not have to rejet. Is this true??
I have a set of TBR's. From time to time, I'll swith back and forth between them and my stock pipes. It runs great either way. I have not rejetted. I did paint the header part of the pipes, though. They were really blue (used) when I bought them.
