Sorry if this is a repeat, I did a little searching and didn't find anything close to my question. I am not super familiar with sportbike exhaust, my cruiser doesn't have a ton of color/material options. Other than looks, does it matter too terribly much on aluminum, titanium, or carbon fiber exhaust? Second question, with slip ons there isn't any adjustments needed for a fuel injected bike correct? Sorry for the newbie questions.
