Hi, I have had my 2006 Speedmaster for about 8 months now and would like to change out pipes for more sound. I am not interested in a power increase, just a sound increase so cars on our lovely Southern California freeways can hear me coming. I don't want to have to rejet if I don't have to. Are there any aftermarket pipes that are reasonably priced that I can put on without rejetting? Thanks in advance for your advice.
