I have Kawasaki zzr600 2007. I want to install the 2 brothers exhaust system in it. Can I just order the one for my bike and install it without ajusting gas or anything in the enginee? Some of my friends told me that I need to bring to the shop to let technician adjust the enginee when I replace the original exhaust system. Is it right? Thanks
it's a good idea to get your bike remapped or dynoed
