Function Over Fashion
Exhaust tips actually do play a role in the final sound of an exhaust. Where mufflers and resonators take care of the good majority of exhaust pulse cancellation and silencing, the exhaust tip can shape the remaining pulses and accompanying sound as it makes its final exit from the pipe. Much in the same way a Tuba sounds different than a Trumpet, a short megaphone exhaust tip will sound completely different than a long pencil-shaped exhaust tip. Some exhaust tips even add a small resonator to the equation to help mellow and deepen the exiting exhaust note. A perforated tube surrounded by sound deadening material puts one last mellowing touch on the exhaust pulses before they reach your ears and the ears of others.

I was going to switch out tips with the factory Crossfire ones, but after reading this I think I'll keep the Ansa resonator tips intact.
