Carb jetting question

[2manywings]

I recently picked up a 2001 Valkyrie. It came with a set of  6 into 6 exhaust that I believe are Two Brothers. I'm not into that sound, so I sold them. The guy that bought them wants to know if he has to rejet the carbs or what other mods. he may have to do. Can anyone direct me?

Two brothers pipes were designed so that you do not need to rejet the carbs.

I believe they are Two Brother pipes. That's the only brand that I've seen that "turn out" at the ends. Maybe someone can correct me if that's not so. Is it common to have to rejet with some brands?

Most aftermarket pipes just use different needles or shim them.
