I got rear-ended and the option of getting an aftermarket pipe has come up, but i've never really been interested in pipe mods before so i don't know jack about them. Aside from knowing the Brand names of the pipe companies, i don't know which ones would work best with my 2002 ZX6R. Any suggestions or recommendations on models and performance issues? How do I choose them, aside from the look and sound? It won't be a full exhaust system mod, just the pipe.
