You want rumble? Change the stock cam to something with longer duration with a lower lsa like 108. Now, go google and then come back with a better understanding of what gives an engine that nice rumble that you seek. Exhaust and cai doesn't do it. Btw, I'm referring to American engines where you can actually change the cam and it's a relatively easy mod.
